So I've been fiddling with the arp (I'm big on arpeggiators!), and it's a tad strange and lacking some vital features imo. From my own feelings I think Novation might be the best company when it comes to arps (with the features available) - very similar to Roland but with a few added extra features in there that tick all the boxes.
Firstly wanted to address the "rate" control - do other people find this is a useful feature (the way it is represented), because to me it seems non-sensical to have the number 25, and have only 5 notches of usability before it goes into non-musical / drone territory, or covered by another feature like Sync. Surely rate could have 'Straight', 'triplet', 'quintuplet', and 'septuplet'. Then combined with the sync you could set sync to be 8th, and rate to be triplet, so you'd get 8th triplets. Or 16th sync and rate of quintuplet, so you get 16th quintuplets (obviously at this stage if recorded the deluge would quantize to triplets or straight divisible notes as 5ths and 7ths only exist through sync-scaling). This would be far more sensible in my eyes, but curious what others think on this rate=25.
My other, more important feature request is with the arp "mode" - could we have some more variants of "both" (maybe better to call it UD for "up down") - UD1, UD2, UD3, etc. At the moment "both" is step 1, 2, 3, 2. Would be useful to have 1, 2, 3, 3, 2, 1, and other typical variants that are prominent in other manufacturers arps. This really has a massive impact when it comes to the octaves set for the arp, as currently if I hold 3 notes on "both" with 2 octave setting I get a normal 4 note up down, followed by a 2nd 4 note up down 1 octave higher (as expected so far), then back down with just 2 notes which is odd, then repeat - I'd expect just 8 notes with 2 octaves not 10. This is also effected by not having the triplet function within the arp, which would allow the arp to deal with the way octave jumps would work in 3 note patterns etc. especially if using UD2 (1, 2, 3, 3, 2, 1) with dual octave which in triplet mode would give 12 notes that fits into a standard bar as triplets.
