I've been looking into the XL7 for a little bit now, but let me get this right. You can't sweep the filter"q". You can only do this during note on. Please tell me this isn't so and be fixed in an OS update. I may have read wrong, and I hope someone here can prove me wrong. I realy like the unit, but for the type of music that I do, this feature is vital to me. Thanks for humoring me. Prana

Currnet Emu filter math used by the DSP in the Proto 2K series does not let the resonance of the filter change over the course of the note. Resonance is fixed at note on. We went 'round about this quite a bit last week. Personally it is an annoyance, as I tend to use 16th or 32nd note runs on stuff I want to monkey with the res on. Can't even notice it then. Cutoff is another matter. That works just fine in real time. With the crazy modulation these things do you can have quite a bit of fun with it too. With luck they will do some work on the filters before long and life will be even better. As has been stated before the fact that the Proto 2K modules are using the 14 pole filter designs (first seen in the Morpheus) requires some pretty hefty math. One of the things that the Emu guys did to get the filters so that a DSP could run them in real time was to limit the number of variables. So resonance got fixed at note on. There is opinion in the group that modern DSPs with their increased power might be able to handle real time resonance adjustments. So far there has not been comment from the Emu folks on this list if this is something that they are tinkering with in the back room, and no comment is expected. There is also some agreement that while the Emu filters might need some upgrading, as the "analog" impersonations are not on part with the ones from most of the VA synths (Novation, Korg, Waldorf) that you can get.

Hi, Recently read something arron was posting about synthesis and decided to put my programming fingers down for a day or two and get reaquainted. so anyway, i'm individualy messing with wavforms on different layers and was wondering. if i have 4 different waveforms with 4 different filters, could i use the quick edit knobs to define cutoff for all 4 diff filters?
2007-10-29 by malik
i just noticed something about my quick edit Res knob. It's not changing Q in realtime!!! I haven't noticed this before! If i'm holding a note. and i mess with it. nothing happens until i release it and press again. then i can hear the result. is this a setting? --- In xl7@yahoogroups.com, "malik" <malik_martin@...> wrote: > > Hi, > Recently read something arron was posting about synthesis and decided > to put my programming fingers down for a day or two and get reaquainted. > so anyway, i'm individualy messing with wavforms on different layers > and was wondering. if i have 4 different waveforms with 4 different > filters, could i use the quick edit knobs to define cutoff for all 4 > diff filters? >

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. SImply unhook the default knob assignment for the knob you want to use, then hook one per layer to the parameter you want to control. -Aaron ----- Original Message ---- From: malik <malik_martin@...> To: xl7@yahoogroups.com Sent: Sunday, October 28, 2007 9:10:33 PM Subject: [xl7] Re: Filter question looks iike i accidentally added myself to a thread from 2001, that answers my second question. too bad that never got fixed(or upgraded). --- In xl7@yahoogroups.com, "malik" <malik_martin@...> wrote: > > i just noticed something about my quick edit Res knob.

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.

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.

Whoa, that did get released? Wow. For the E4's tamer filters, it wasn't really a problem. On the P2k/XL-7 side, the 12th order filters were a little, um, excitable. =) I do seem to remember there being two cord destinations, one for RT Q and the old one for note on Q.

The artist formerly known as rEalm referenced an unreleased Command Station OS that had the realtime filter controls (resonance). http://groups.yahoo.com/group/xl7/message/15123 > Why do you want an older OS?

Wow. For the E4's tamer filters, it wasn't really a problem. On the P2k/XL-7 side, the 12th order filters were a little, um, excitable. =) I do seem to remember there being two cord destinations, one for RT Q and the old one for note on Q.
