Roland SH-101 Programming Tutorial (part 1 of 4)
I start this tutorial series with a quick playing demo, and then all about ADSR envelopes.
I first of all look at the VCA, here the ADSR envelope shapes the duration and volume of the sound. I then go on to use the envelope in conjunction with a gated note (on/off), the VCO and envelope only.
Now I look at the filter, again in conjunction with the ADSR.
It will make more sense as you hear the results of my explanations by watching the video.
