Word - with that in mind (feeling jealous or left out or whatever, basically - wherever I was about 36 hours ago) Iāll look into what a person would need to do to get the Keys vibe.
It doesnāt have the DPro machine where you can ādrawā between two waveforms and you cannot upload any user waveforms. Ironically I feel youād mostly want that to articulate playing on it.
Iām going to have to see if the keyboard input records note-off inputs (func+trig pressdown on the seq mode) to handle the release stages of voices; because now returning to program the machine, I care about the amp curves of things a lot more.
i.e. you can set the attack (this is a general mnm thing I presume) to something really high like 120 and I thiiink having a succession of multiple notes whom do not retrigger the amp stage (you have to flip over to the env trig edits and remove amp) will make the curve either gradually get faster with each trig that happens, or slower, not sure - but the successive notes make a difference; goal being to articulate the onset curve without using any param lock data.
and I figure you can do the same with note-off trigs as well (the yellow ones).
I really do prefer using key-based versions of synths for anything that was ever designed in-house with keys. i.e. I have a virus ti-1 desktop version but one loses out on polytouch if theyāre using any step sequencers where the velocity articulation and note entry are separated (for entry-level users rather) as opposed to the immediacy of the keyed response.
and for analog keys, for example, aftertouch is there and it also has a joystick.
analog keys for 660 might be the nearest thing you can get to for a low price-point and some good footprint of capability. I havenāt really been able to use the digitone keys 
But I want to do a kind of comprehensive review of this device for people who donāt own it to know what they are missing out on, from any perspective; i.e. factory content not being evaluated fully (the joystick, mainly, and how it can be used to do that pole/scene thing I described) and also how to not feel like you are missing out on it. The things fucking heavy. itās probably just a collector thing and Iād like to quell the whole desire to find one just to say āI got one.ā
btw I got one (jk)
and ideally to suggest some kind of simplest setup to get yourself feeling like you have the keys version using equipment you can acquire today for the cheapest would prob be the abs main goal of the review. Iām talking about a youtube video or something.
in it I will also fuck around with (if weāre going to incorporate a PC to emulate the idea of having a Keys version) avoiding menu-diving headaches (Iāll coin a word for this, has something to do with the skull ache pressure of being too far underwater, or your skin wrinkling from being underwater too much ) and how using sysex sends to adjust kits since you -can- do that with a PC would ultimately make your setup more powerful if you just have a desktop.
If you like these ideas or think Iām missing anything, let me know! Thanks
