I recently have been trying extra DSP's and pushed my cards pretty hard. Just added a 15 DSP booster to replace my 6 DSP booster. Needless to say it is so nice to load up so many synths. But some patches in Solaris that I've made need large amounts of DSP. So I lower voices on other synths to meet my required needs. But my dream device is to be able to lower the voice counts on synths through MIDI, so I don't have to fumble in the dark with mouse. In between our songs it's lights out. It just looks real cheezy also. But I can imagine that any live player wishing to keep the same project loaded all night could be very happy about this. Any possible way to achieve this.
Your Fumbled Servant,

Hi, that feature is there but the devices haven't included the voice as a parameter change. That is cause when you change the number of voices the sfp does some work with the dsp rearrangement that is to hard for actual real time control. Best way is to record to audio, turn voices to zero. You will see, there isn't any real advantage working just with midi, that's something it took me long to find out...

hoi scope4live,
If by any chance you use a couple devices with old preset list, they're the only ones that allow remote poly changing: the polyphony may be stored along with each preset. So selecting a preset that's saved with 0 voices could free up some DSP cycles.
Another trick that may save a bit DSP is to remote disable options/insert effects, which can be done using presets or with assigned MIDI CC#.
Unfortunately, I don't think there's a lot more you can do to realtime reduce DSP load.
Also, I noticed that SFP isn't always happy reloading it's DSPs on the fly like that. DSP use may become 'fragmented', possible leading to nasty "DSP overload - do you want to reload" messages.
[edit] Oh, hadn't noticed we were in "Device/Module Wishlist" forum. If it could be implemented, it would be on OS level (CW), and/or developers would have to enable it for each device - read: rewrite the device.
Hope this helps,
at0m.

Good tip Atom. Thanx,I will search the synths like Saturn and such. This is a trick that I was unawre of. It is a great idea, I am now thinking I will be able to find an alternative way. What if I changed my name to Scop4pendajos?
