They're not DSP chips, well, at least not general purpose DSPs. They're custom built ASICs which do nothing but filter with either 6-pole filters, cascadable 12-pole filters, or fixed 14-pole filters. They are really awesome chips. I'd use them in a heartbeat if they were still made and I was making a hardware synth. The MIDI B (Filter Q) knob will control whatever MIDI B is hooked up to in the patchcords section. By default, it's hooked to Q on all layers. Simply disconnect it from the ones you don't want. The Command Station is a completely programmable synth. The fact that they're silkscreened on the front is for convenience only. You can connect them to whatever you want. While you're downloading eLoader from the link I just sent, I'd download the manual and read through the patchcords section. It'll make it all a lot clearer. -Aaron ----- Original Message ---- From: malik <malik_martin@...> To: xl7@yahoogroups.com Sent: Tuesday, October 30, 2007 3:31:00 PM Subject: [xl7] Re: Filter question wow that's too bad about the DSPs. If you ever program something new. would you use those same DSPs again? if yes, why? cool. i would like to control a sound with 4 different filters at a time(i feel like making a track right now!) but my real question was, will the quick edit FilterCutoff knob edit the cutoff of all 4 layers, for each filter that was chosen? or under 1 global filter, if that makes sense? --- In xl7@yahoogroups.com, Aaron Eppolito <synthesis77@...> wrote: > > Yep, Q is note on. I posted a long time ago about "faking" Q with a duplicate layer. Simply duplicate the layer you like, turn Q all the way up on one and down on the other. Then, route a controller to volume on the one with high Q, essentially fading in the Q layer with the knob. Sounds really good. > > > We had a test build that tried to do realtime Q on the E4, but it was pretty glitchy sounding. In a nutshell, the filter chips only have one interpolator, meaning you either get realtime Fc or realtime Q. To do both, you have to continuously pound the chip with new filter coefficients and use the interpolator to slam between the two. It doesn't work so well in practice - there were a lot of glitches and filter instability. > > > And, to answer your original question, yes, you can have 4 different layers with 4 different filter knobs.
