I was just wondering whether anyone knew if it was possible to control the filters/resonance etc. of the individual drum sounds on channel 10 via MIDI on the XP60? Before people jump in and answer I know that the drum sounds on channel 10 are set and when using the sequencer only the whole of channel 10 can be controlled (apart from velocity length etc) but when in Rhythm mode it is possible to edit the drum sounds in real time (I'm not talking about trying to change the drum patch just the freq/ cutoff etc. in the Key TVA/TVF menu is there anyway of implimenting this via MIDI???
PLEASE HELP!!!!

I'm wondering what you mean by MIDI. (1) Do you mean using controller messages? (2)or do you mean pressing buttons or moving sliders?

[This first part may be of no interest to you at all; sorry; I was just unsure what you meant]
(1) Rolands SoundCanvas series allowed you to control some paramaters on individual drum hits (e.g., a single snare or cymbal or something) using CC98, 99, and 6, but I don't think that was implemented on the JV/XP series. And even then, the only parameters you could control were coarse tune, level, kpan, reverb send, chorus send; I don't think you could tweak filter cutoff or resonance).

On the JV/XP series CC71 controls resonance (TVF), CC72 decay time (TVA), CC 73 attack time (TVA), and CC74 Cutoff (TVF). I know you can control Tone Level using CC 80, 81, 82, 83, and CC101/100/6 can control coarse or fine tuning per patch depending on the value of CC100.

So what does this mean to you in rhythm mode?

CC99/98/6 were used on the SoundCanvas to control Filter Cutoff and Resonance. The problem with the JV/XP series is that there is no way to stipulate rhythm instrument (key) number. On the SoundCanvas, CC99 on channel 10 stipulated parameter (level, pan, etc.) and CC99 stipulated rhythm instrument (note in the rhythm kit). CC6 was the amount of change.

So you could try that on your JV/XP on channel ten, but I don't think it works. For some reason, Roland seems not to have implemented this on the JV/XP series.

More likely:

(2) To do it by pressing buttons, you'll be using sysex. In rhythm mode, go to the instrument you want (e.g., a cymbal) and go into its editing screen. With (a) Transmit Edit on and (b) your sequencer recording on an empty track, try pressing the button of whichever parameter you're trying to edit in real time. The sysex you're generating should be recorded into your sequencer. When you play it back, it should tweak that rhythm instrument just the way you did while recording.

I've never done this, but in principle it should work.

The problem you may run into is that you're probably going to be generating a lot of sysex, which may result in some MIDI slop or latency. If it does indeed work, go back and THIN that data several times until you get the effect you want with the greatest amount of thinning (i.e., with the fewest sysex messages).

Again, I've not tried this, but I think it should work.

I don't think you can use the sound palette; notice that the lights don't go on when you're in rhythm mode. Bummer.

Good luck.

cheers dnarkosis,
I haven't tried yet but sysex is something that hadn't occured to me. I'll try it and get back to you.

Another thought:

If you'd like to try to use the Sound Palette sliders, one experiment you could do would be to assign rhythm waveforms to a patch the way we've discussed before. Then the sliders will indeed address the tones of the patch, which are your rhythm instruments.

BTW: I did discover (with someone else's help) that you can't use the copy function to copy rhythm settings from a rhythm kit to a patch when you use rhythm waveforms this way. That is, say you wanted a certain cymbal from a certain kit to be assigned to tone 1 in a new patch. You can't use the copy function to copy that cymbal's rhythm-kit settings over into the patch/tone. Another bummer.

But good luck.
