<html><body><font face="Helvetica">For iPad users, the VirSyn app AddictiveSynth is another way to play with filter banks. With this app you draw both waveform and filter response on the screen by hand. Unfortunately, it is not very quantitative or precise, but it is easy to quickly draw a zigzag filter response with a few dozen peaks and play a sawtooth or similar waveform into it. Then you can use the xy controller to vary the amount of fm from an lfo into the oscillator to hear the timbral enhancement.<br><br>Ian<br><br><br><br><br>Sent from XFINITY Connect Mobile App<br><br><br>------ Original Message ------<br><br>From: Bernard Arthur Hutchins Jr<br>To: synth-diy@synth-diy.org<br>Sent: July 3, 2017 at 1:06 PM<br>Subject: Re: [sdiy] Resonator type filters<br><br>A lot of questions here about how a filter bank is used and what it sounds like are addressed in EN116 which I posted. <br>
<br>Basically, if nothing moves, it sounds like nothing: like sawtooth in, different complex waveform out - equally boring. If something does move (modulation, starts/stops, live music) it sounds tinny. I remember well listening to music on the radio through the bank, turning the Q up, and discovering that the western music sounded like eastern music. Possibly a useful reference comment.<br>
