Hi Rui,
I'm trying to learn synthv1, and it would be super helpful if you can kindly help here:
I'm reading the Welsh's Synthesizer Cookbook book and would like to use his generic patch on synthv1. Here is an extract from the book as an example:
1) Is it possible to "convert" this patch to synthv1? If yes, could you help? I think this would be great for future references :-)
Thank you
re. Help to convert Welsh's Synthesizer Cookbook patches
Sure.
As only 2 oscillators are used you may well only use one engine on synthv1, either "Synth 1" or "Synth 2", by turning the OUT Volume to 0.0 on the chosen one out.
Now you already know how to have a triangle wave: DCO Shape 1, 2 = "Saw"; DCO Width 1, 2 = 50.
Tune on -2oct means both oscillators are tuned 2 octaves dow, so set DCO Octave = -200.0.
Mix on 0db 100% means that both oscillators are balanced, so keep DCO Balance = 0.0.
Turn the LFO off, it won't be needed as from the generic patch above.
For the Low-pass filter you should simply keep DCF Type = "LPF" and DCF Slope = "12db/oct", then set DCF Cutoff = 100.0 and DCF Reso = 0.0; as there won't be no filter envelope, you should turn to DCF Envelope = 0.0 and that's all for the filter stage.
Now comes the tricky part :) the Amplifier envelope (DCA in synthv1)... you may set DCA Attack = 0.0 (A) and DCA Sustain = 0.0 (S) already.
The big question now is how to set the 0.12s value for DCA Decay (D) and DCA Release (R), right?
Ok. Look the current value of DCO Env.Time, which makes for a percentage (%) of the maximum running time of each stage, which in turn is hard-coded to 10s, which means that, for a current value of DCO Env.Time = 50.0, makes it for 5s in total per stage. From this simple calculation, 100 * 0.12s / 5s = 2.4, gives the correct value you should set to DCA Decay = 2.4 and DCA Release = 2.4.
Wasn't that easy enough?
Hope that helps.
Cheers

Here what I did:
I don't know if I did something wrong, or I'm expecting too much. But the patch doesn't sound like a kick. It's more to a brass than a bass. :-)
re. When you explain it's easier
you probably overlooked the DCA Sustain = 0.0; cf. Amplifier (S)ustain proposed to 0s.
otoh. please note there's no plain promise that it's going to sound exactly like a real kick drum whatsoever
the recipes in the said "cookbook" are just for starters hints only... you'll have to tweak it out quite a lot to make it sound as you probably expect for real:)
remember that experimentation is root to all science :)
byee
You are right. Thank you for
