Wavestation Mailing List FAQ

(Frequently Asked Questions) version 1.3
October 19, 1996.

This document is revised frequently to include more information, correct errors and outdated information, and answer questions more comprehensively.

The Wavestation mailing list is a discussion forum for users of the Korg Wavestation series of synthesizers. This document contains information about the synthesizers and about the mailing list. It will be posted to the list approximately once per month. The most current version is also located at http://www.magic.ca/~lost/faq.html.

If you would like to contribute, please e-mail me at lost@astral.magic.ca. As with version 1.x of anything, there are likely significant errors or omissions; and I would like to know about them.

PART I: KORG WAVESTATION.

1. What is the Korg Wavestation?

(a) Wavestation Overview
The Korg Wavestation (also known as the WS - and the two terms are used interchangeably throughout this document) is a family of synthesizers developed by Korg, Inc., based on a mixture of different sound synthesis technologies. The Wavestation re-introduces vector synthesis, originally present in the Sequential Prophet-VS, and which later appeared in the Yamaha SY22/TG33/SY35. The Wavestation also introduces "Wave Sequencing", an enhanced implementation of the dynamic wave shapes originally available on the PPG Wave series and later as "Transwaves" on the Ensoniq VFX and its descendants (SD/SQ/TS series). Historical Note: New England Digital's Synclavier Resynthesis software allowed time-based crossfading of additive-defined waveforms, back before the Synclav was a sampler. (Resynthesis used the additive/FM hardware.)

The Wavestation allows synthesists to create sounds by combining waves created using the above methods, as well as other traditional synthesis techniques, and processing them through an on-board effects processor. The result is a great-sounding instrument.

In the opinion of the writer, the Wavestation lends itself best to very complex sounds which evolve over time. Thanks to a very flexible complement of on-board effects and EQ, it can be made to sit very well in a mix with minimal fuss at the mixing console.

(b) Synthesis Architecture Hierarchy
(i) Oscillators
At the lowest programming level, the Wavestation has "oscillators". Oscillators play waveforms which are built in to the instrument and which may be available via a PCM card plugged into the front panel. Each oscillator can be designated to simply play one of these waveforms, or to play a user-defined "wave sequence" (more on that shortly). In addition to being able to assign an oscillator a wave, you can also adjust its tuning, and other parameters which are beyond the scope of this FAQ. The Wavestation has 32 such oscillators, which means it can make up to 32 sounds simultaneously.
(ii) Wave Sequencing
Now, about those wave sequences: The user can put together a sequence of waves which will be played back each time the oscillator is triggered (i.e. by playing a key on the keyboard). A sequence could be a series of waves which in which there is only a subtle difference between each - so that as the sequence plays back, the sounds seems to evolve. For example, you could create an 8-step wave sequence that starts out with a very dull wave and each wave after that gets progressively brighter. When a key is played, the sound will become brighter as the wave sequence plays back. This is the most basic use of wave sequencing.

The flexibility and power of wave sequencing in this context lies in the ability to decide what source you want to modulate the wave sequence with. It can be set up to play the waves chronologically from start to finish, or you could create a wave sequence that you is stepped through using the key pressure, for example. Using this technique, a sound could be soft until you put more pressure on the keys, which in turn would cause the wave sequence to move to a later (and perhaps brighter - or whatever) phase. Korg makes such wave sequencing very viable by providing waves which are very similar to one another. For example, there is a series of waves in the instrument which are sampled from an analog synthesizer; the first of which has the filter almost closed, and with the cutoff frequency becoming progressively higher as the waves progress. Another series of waves consists of looped samples from a single performance of a saxophone note - at various stages.

Wave sequences can also be used to create rhythmic effects. Using the Wavestation's drum waves, for example, complete drum patterns can be created by simply creating a wave sequence that uses the instrument's percussive waves, many of which are samples of real drums.

(iii) Patches
A PATCH consists of up to 4 oscillators, each playing back a wave or a wave sequence, mixed together using a vector envelope. At the patch level, synthesists can "hard sync" oscillators together, add filter and amplitude envelopes (of the 4-stage rate/level type), and LFO effects for vibrato.
(iv) Vector Envelopes
What is a vector envelope? The Wavestation keyboard and Wavestation A/D feature an analog joystick in a diamond-shaped patern along two axes. Each corner of the diamond represents a different oscillator. As the joystick is moved closer to each corner, the wave (oscillator) associated with that corner becomes louder. If the joystick is moved all the way into one corner of the diamond, only that sound will be heard. If the joystick is in the centre position, all oscillators will sound at equal volumes. A vector envelope is created by storing up to four such positions of the joystick. The Wavestation will then perform a smooth transition between the recorded positions over a time period specified by the user. Vector envelopes may me looped to create a continually shifting sound.

Up to 35 patches of up to four oscillators each may be stored in a Wavestation memory bank. (Different Wavestation models have different numbers of memory banks, see Item 2, "What are the differences between the Wavestation models?")

(v) Performances
Up to eight patches can be combined to form a "performance". A performance consists of up to eight patches, which can be assigned to sound only in a given note or velocity range; mixing, panning, transposition and detuning assignments, and an effects patch. Normally, when you play a Wavestation, you play performances.

Up to 50 performances may be stored in a Wavestation memory bank. The 50 performances may draw upon any of the 35 patches stored in that bank. Performances may actually use any of the patches stored in any other bank, although this is not generally considered to be good programming practice, as it makes patch/performance relationships difficult to keep track of.

3. How do I restore the RAM banks to the factory settings?

Korg has a ROM card set (WPC00P), which has two cards containing the RAM1 and RAM2 data. The A/D's RAM3 is the same as the Wavestation EX's ROM card (except for the last 5 Performances).

The SR's Bank 3 is equivalent to Korg's WPC-12 program card.

Contact your local dealer for these; they should be priced considerably lower than the other cards. If you can't get the cards from a local dealer, contact your nation's distributor. A list of national distributors came with your WS.

You can get the contents of the RAM banks from the Wavestation Trading Post at http://www.his.com/~rickg/rick.html, or via anonymous ftp at louie.udel.edu:/pub/midi/patches/WAVESTATION

It is also possible to dump the RAM altogether, which is more useful if the data in your Wavestation should become corrupt. Refer to section I.7 of this document for further information.

The following note from Dan Phillips of Korg explains why the ability to restore the factory RAM sounds is not built in to the Wavestation.
"... please note that INIT RAM will not restore RAM banks to their factory states. So, you may ask, why not? It is true that some (though certainly not all) devices store this info in ROM, allow the user to reset to the factory state. This is fine if the amount of data is really small, or if the amount of ROM available is particularly large. Neither of these are the case in the keyboard or A/D (Wavestation banks are ~32k apiece, and the ROM is quite full).

On the SR, we did have the option to do this if we so desired...at the expense of 3 of the new ROM Banks. We basically asked the voicing and product guys which they'd prefer: 150 additional sounds on board, or backups of the factory RAM. Their response was, as we expected, in favour of having the most sounds possible...and I hope most users would agree, as well."

4. My WS makes a high-pitched whine, is it defective?

A part in the LCD display of the keyboard and A/D makes this noise. This seems to be the norm rather than the exception, so don't worry.

(Does anyone actually have a WS that doesn't make this noise, other than the SR?)

Has anybody found a fix for this problem?

5. Can I import my own samples into the Wavestation?

I just checked the music machines
(http://www.hyperreal.com/machines/) site and there is indeed some info there on the SAM-1, by Zadok in the Netherlands... lets you load samples into its ROM and plugs into the WS PCM slot. The SAM-1 could read disks or accept SDS sample dumps.

I say "could" because I remember reading here that they had folded. Contact info:

fax: 31-70-3.200.345
This info is from Dan Phillips, from the old WS list archives.

If someone gets in touch with them, let us know!

6. I've downloaded patches from the internet. Now what?

We'll assume you've downloaded your files from The Wavestation Trading Post WWW site. Here, all of the files are stored in bulk MIDI Sysex format, and compressed using the DOS PKZIP format. Most platforms can un-ZIP these files, and they have to be ZIPped because they're positively huge and take up a lot of hard disk space if they're not.

You will first need software to unZIP the files. For DOS, it's PKUNZIP. For Windows, it's WINZIP. For the Mac, you can use "ZipIt" or "StuffIt Expander". (Please note if you're using Stuffit Expander, you will need "DropStuff with Expander Enhancer installed). In each case, documentation comes with the software in question to unZIP the file.

After the file is unZIPped, you need to feed it to the Wavestation. Some sequencers are able to read the sysex file, as are some librarians. For the Mac, try "Bulk Sysex".

Remember that your Wavestation's memory protection needs to be turned off.

These instructions will be elaborated upon further in an upcoming version of the FAQ.

7. How can I use the Wavestation's "Special Page"?

Note: using the special page can cause your Wavestation to do all sorts of strange things if you do not know exactly what you are doing. A couple of incorrect keystrokes could make your Wavestation go into never-never-land - and never-never come back - at least until you physically open up the case and remove the battery for a few minutes.

From time to time, your Wavestation's internal operating memory can become corrupt which can cause your Wavestation to act strangely. It may be necessary to re-initialize the unit. This is done using the Wavestation's "Special Page" (which also has additional functions, which will be included in a future revision of this document).

Before even going near the "special page", it is imperative that you back up your patches, wavesequences and performances to a prog data card and/or to a MIDI system exclusive storage device such as a computer. You will lose everything in the RAM banks, including factory programs.

For the keyboard and A/D
Wait for the KORG logo to come up, then press Down Arrow and '4' at the same time. A diagnostics page will appear, including the software version of your Wavestation. Press CONT to get out of the page. Do NOT press any other keys unless you know what you are doing. That said, the INIT RAM soft key will initialize RAM and copy ROM over RAM1 and RAM2 on the EX.

For the SR
At any time (not just at startup), press simultaneously the down cursor and the BANK, EDIT, and +1/YES buttons. To exit, press PERF, MULTI, or MIDI/GLOBAL to go to those respective top-level screens, as usual (MIDI/GLOBAL will ask "are you sure")

Pressing PAGE+ once brings you to the HELPFUL PAGE, used for reports during debugging, and pressing PAGE+ again brings you a screen listing the software engineers for the Wavestation product line. You can exit from these other pages as described above.

Please read the note from Dan Phillips of Korg Inc. regarding INIT RAM found in section I.3 of this document for more information.

8. Why am I having trouble with rhythmic Wave Sequences?

This material on rhythmic Wave Sequences is exerpted (with slight adaptation) from the SR manuals by Dan Phillips, (c)1992 Korg Inc.

The original idea for Wave Sequences was for a smooth, gradual transition from one timbre to another. Shortly before the Wavestation's release, however, Korg's voicing staff discovered another application: the rhythmic Wave Sequence, using abrupt changes in timbre. Some examples of these are The Wave Song (ROM11, #0) and MIDI Clock Song (ROM8, #10). Typically, smooth Wave Sequences use crossfade times of greater than 10 (often much greater); Rhythmic Wave Sequences, on the other hand, use crossfades of only 0-2.

Many of the factory Performances use rhythmic Wave Sequences to trigger drum sounds; you can also create interesting rhythms out of timbral shifts alone, by juxtaposing PCM Waves of different brightness, volume, and harmonic character.
