RADIAS I03 WahGuitars

I'm trying to deconstruct the RADIAS' default soundset patches and I've come across several which have one timbre that affects the others--like the WahGuitar (I03): the first 2 timbres are arpeggiated by the third timbre. How is this this done (I'd like to use the idea on my own patches) and how do I get in there and change the rhythm? Timbre 3 has an arpeggiator (sans step sequencer) and although all the arp steps are on the rhythm doesn't seem to reflect this.
Anyone out there who understands this patch, could you please explain?

Just took a look at that patch in the editor ...

I can see that in Timbre 3 OSC1 is set to Audio In, and it is sourcing audio from the Internal Bus. Timbre 1 is routed to the Internal Bus so Timbre 3 is processing audio from Timbre 1 only, rather than Timbre 1 & 2.

Whatever comes into Timbre 3's OSC1/Audio In is then processed through Filter 1 which is modulated by Timbre 3's Mod Sequencer ... so it's that puppy you want to edit to change the rhythmic effect.

To use a Timbre as a filter effect like this yourself the steps would be :

Set one or more Timbres so their Output Balance sends some (or all) of their output to the Internal Bus. In the Timbre that will act as an effect, set OSC1 to Audio In mode and set the Source to be Int. Bus. Then do fun things with filter modulation etc. etc. etc.

The Timbre operating as an effect should be assigned to MIDI channel Global so that it gets triggered by the keyboard and lets audio in.

unbelievable--
I had no idea the RADIAS could go this deep. Internal busing? tres cool.

This internal bus thing was one of the great features of the older Viruses (my B has it) and then disappeared in the TI and turned up in the Radias ... maybe it moved home

Hi,

has anyone found a possibilty for using the internal bus in cross modulation? I want to setup some algorithms (FM) like in DX/ where you have a modulation chain, e.g:

Timbre1 VCO -> modulates Timbre2 VCO -> modulates Timbr3 VCO

Many thanks in advance.

Ciao, Dirk.

Off the top of my head ... I don't think you can do things like that because the internal bus is not "per voice" but rather "per timbre". So what comes down the internal bus is a mix of all the voices generated by a timbre. You would get away with it if your program was supposed to be mono.

In the case you mention I can't imagine how you'd get the stuff coming down the internal bus to directly modulate the VCO at audio rate. You could however drive it through the Waveshaper or use RingMod.

Just a few random thoughts on that ...
