Question Subtractor question: what is the scale of the controls?

Recently I bought Fred Welsh's Synthesizer Cookbook and I've been trying to program the patches of the book into the Subtractor. However, the settings for each patch are given in db (oscillator mix), Hz (LFO rate and filter cutoff) and seconds (attack, decay and release) while in the Subtractor they are always a pure number, normally varying from 0 to 127. Following indications in the book, I programmed a patch using a sound editor to calibrate the settings but the process is laborious and slow. It would be much better to know the scales used in each control. Iīve noted that the scales arenīt linear. Maybe they are exponential/logarithmic? Unfortunately, I couldn't find anything about this in the manual.

If anyone can help me with this, Iīd be very grateful.

The most controls are exponential. I'd recommend you to use Thor instead. All controls in Thor have scales in the needed units (Hz, ms etc.). Otherwise I've never looked at the numbers. Trusting your ears is more worthfull then adjusting everything by given numbers.

Thanks, iGoA, Iīll do that. Besides, many patches use oscillator sync and Subtractor doesnīt have this feature. The manual says you can use FM instead, but I canīt see how. It seems to me they are completely different things.

I'd say, they ARE different things. I wouldn't know how to use FM instead of sync.

Yes, but the manual says: "A seasoned synth programmer using Subtractor for the first time may wonder why the Subtractor oscillators (seemingly) cannot provide the commonly used pulse waveform and the associated pulse width modulation (PWM). Or oscillator sync, another common feature in analog synthesizers. The simple answer is that Subtractor can easily create pulse waveforms (with PWM) and oscillator sync-sounds, and a lot more besides, partly by the use of phase offset modulation."

Now we're talking about PWM which is yeat another different thing beside FM and synced OSCs. What are you asking now? ;-)

Nothing, but it would be much more honest and straightforward if the manual simply said that Subtractor isnīt capable of syncing oscillators...
