Each part can only have a single arp running at once. Splitting Parts or being more creative with the arp itself is what's needed.

Depending on what you're doing you may be able to use velocity zones where one pattern is at one velocity and another pattern at another velocity. Then you could have one octave respond to one velocity (or range) and another octave to another velocity (or range) so you end up with different arps depending if you press C1 D2 or E3 (or C1, C2, and C3 as trigger notes). There are lots of constraints (and setup) with that approach but may work.

Thanks Jason. I'll give this a try. Now that I also have a MODX8, I think this constraint may not apply to that synth so maybe I'll just use the MODX when I need to have multiple arpeggios across a range of keys/notes.

I'd like to have a performance with a guitar voice (e.g. "Some Hair" ) in Part 1 and various other voices in the other 3 parts. I want to be able to assign different arpeggios to the notes C1, D1 and E1 for only the voice in Part 1. I realize you can have different arpeggios in each of Arp1, Arp2, Arp3, etc. But this is specifically for a single "Arp".

Up until now I have had to create 3 parts with that same voice and assign a different arpeggio to each part.

The Arpeggiator is designed for an entirely different purpose, the different keys give the unit the information it needs to be “chord intelligent”. Therefore, you do not want to look to the Arpeggiator as the way to accomplish this… even though you can use “Fixed” Note as the Convert Type which eliminates the chord quality adjustment so that the Arp phrase will play back exactly what you played (as in Drum Phrases).

However, the user access to Arp phrase construction is really not about putting multiple phrases such that each key has a different phrase.

This can be accomplished via other methods — we have a tutorial in the Motif XF LEARN area of this site that outlines how you can have each Key trigger a different audio loop. The Audio Loops were created using the XF’s Pattern Sequencer… each Pattern Section was resampled as an audio wave and assigned to a Key.

And there’s a follow up article outlining how the data was prepared… built up from Arp Phrases.

Now neither the MOXF, nor the MODX are samplers (like the Motif XF was), but you can use your computer to record/edit the Audio and create the Wav data. You can move the audio data to the MOXF or MODX as .wav and recreate the same thing.

The articles feature a Download (example) showing you how it’s done… it should be able to load to either MODX or MOXF (if you have a Flash Board installed). You’ll see how I used the Pattern mode to create the phrases. (Edit — If links are not working we’ll try to locate the data)

There are some sample libraries that feature tempo specific drum grooves where each Key has a different drum phrase… holding two or more keys combines the grooves. Because you can import audio data directly to the internal MODX, you can pretty much configure whatever you’d like.

Thank you, Bad Mister!!!

I've long thought about using the MODX as a primitive looper, but thought I was over thinking it to consider it in this way.

But this has confirmed that it's a thing, and that I should pursue it.

Cheers!!!
