Steiner Synthasystem Progress - VCA Now Working!

See the post on Analogue Realities. According to David, Nyle Steiner currently has a sequencer, VCO, VCA, and EG working. The full Synthasystem will come. I'll only be posting major updates, so be sure to check out the rest of Analogue Realities for more. If you have an RSS reader be sure to sub to it for updates.

Update: some more info of what's to come via David.

"I will eventually offer:

1. VCO type “A”. The Synthasystem also had a type “B” and “C” which were scaled back version of the type “A”. Since the Type “A” does it all, I don’t think I’ll re-issue the others unless there is some demand)

2. VCA/Mixer

3. VCF (the “real” original Steiner version. There is a difference in how Nyle did the resonance as compared to how those doing tribute filters typically do it)

4. Four different EGs.

a. ENVDL #1 – Duration Level

b. ENVDL #2 – Duration Level with a switch which converts the attack time to a delay time

c. ENVDT – Instead of duration level control, it controls the duration time. It also has a switch to convert the attack time to an initial delay time

d. ENVVD

One will be the Triple Envelope Generator which combines #1, #2, and #3 above. It’s the one which was in the Synthasystem. The fourth is one I don’t think Nyle ever released, but I’m going to. It has a variable damping. I haven’t built it or seen documentation other than a schematic I found digging through Nyle’s archives so I’m not sure what it’s controls really do. The end user can build these all separately if they want to.

5. Voltage Sequencer

6. Frequency Divider

7. Two voice keyboard

8. “Multiphonic” Keyboard (very cool controller)

9. Noise generator

10. Peak Selector

11. Phaser

12. Ring Modulator (Nyle is toying with the idea of changing this from using the MC1495 chip to discrete components based on his VCA design)

13. Sample and Hold

14. Selective Inverter (honestly, I haven’t quite figured this one out yet. Nyle tried to explain it to me but I didn’t quite get it.)

15. Tuner/Monitor

16. Input Pre-amp

17. Voltage Controlled Trigger Generator

18. Voltage Follower (basically a slew rate limiter or portamento)

19. Voltage Processor (generates different combinations of normal and inverted outputs of an input signal)

20. Power Supply panel/distribution.

21. Trigger converter. This is not a Steiner design, but something people will need to use these in modern modulars. The Steiner modules uses S-Triggers like Moog. This is a daughter board or a separate module to convert between S-Triggers and Voltage triggers. For example, you can piggyback one of these to an EG PCB so that you can seamlessly use voltage triggers on the front panels.

As a timeline, I am ordering some PCBs this week. Actually as soon as I get this email written J I am ordering what I hope will be production boards. I have some SDIY’ers who have offered to stuff a PCB or two to test the PCBs, BOMs, and build notes. So, In a month or two, I should actually be able to start offering the first few core modules, VCO, VCF, VCA, EGs, and sequencer.
