help creating arpegiator

Postby jaykebaldwin89 » 06 Feb 2013, 14:03

I have a nord modular g2, i want to design an arpegiator effect with it to work in conjunction with my digitech whammy for my guitar. i want to create 4 sequenced patterns for this effect, but to work in a particular order for a song i have written, but allow for an intro and bridge. for example, intro runs sequence 1 for 4 bars, follows up with sequence1, then 2 then 3 then 4 for the main part of the song in repetition for so many bars. bridge follows as sequence 1 for 4 bars followed by the main part again. then an outro of 4 bars.
the idea of each sequencer is to control my digitech whammy to there own individual pattern when each sequence runs through. eg;
sequence 1= -1oct, unison, +1oct, unison, +1oct, unison, -1oct, unison, +1oct, unison, +1oct, unison, -1oct, unison,+1oct, unison on my digitech whammy.
this is just an exampple of what i want. i need 4 differant patterns as each note is supposed to create different pattern and there are 4 notes/chords to play in the song.
if there is anyone who can help me with this i would much appreciate it
also, if it can be done with just the g2 with out having to run extra cable to a digitech whammy, then please by all means make suggestions, after All its just the pitch of the guitar i want to change lol

Hi Jaykebaldwin.

You may want to have this topic appearing in the Modular forum. Maybe any admin an work this out.

I guess you have to use a "PITCH SHIFT" module - sorry, I can't remind the exact name but not a "freq shift", whose frequency will be controlled thanks to a sequencer module. I don't remember whether the pitch shift module has a modulation input for its frequency though, but I guess it has.

Second step is to program your patterns in the sequencer. I don't know if it's better to have as many variations as different patterns or as many sequencers modules in you patch. The point is you will have to trigger the change of pattern yourself, say using a fottswitch. And I'm not sure it's possible to tell a patch to change the variation. You could do it through a MIDI message, though.

Good luck!

Thanks, what iv done so far is set up a bunch of level sequencers to sequence the patters for the whole song, all in series so it will run through the whole song then cut ou when its finnished, but i dont know if its best to send the signal from the sequencers to a pitch shifter module/ freq shift module in my editor program or to send it to a midi out module that i can then use to control my whammy peddal to control the changes in pitch via that. Eather way i should get an interesting result, but he other problem is that i want to activate the first sequencer by en external trigger so it doesnt start on its own so that way i have time to make sure my guitar is working properly before a perfomance. Is there a way to get the 1st sequencer to start with an external trigger like a foot switch or something? If so how would i set it up on the editor?

Ok so iv made further developements with the project, iv configured one of the loops i need to work with my digitech whammy, basicly what i did for one loop to work is set up 3 sequencers to control 3 differnt programs on my whammy peddle, 1 for +1 oct one for -1 oct and one for +1 oct effect off. All sequenced in the pattern i want for the 1st loop/ sequence. So far it sounds perfect. But it only does the one sequence out of the 4 that i need ot to do. Ill set up the other sequences tomorow but ill then need to find a way to play them all in the oder that i need them to play, and for that ill need help with. Thanks for your help so far its been great

About the G2 pitch shifter vs. Whammy question, trust your ears.

About the pattern chaining, I would use multiplexers modules. They are likely to be in the logic category. Consult the manual about these so that you have a better idea of what they do, and try to delegate them the chaining duty.

Is there a way to program the g2 to receive midi messages to scroll through variations?

It's already programmed to do so. The manual discusses this on page 62. Variation is assigned midi cc#70...send the appropriate message and variation will shift accordingly.
