Keystep 37 strum-feature via CV?

[tamasgal]

I was wondering if anyone has ever gotten the strum-feature working via CV or has an idea how to get it working with a MIDI converter? I have not used MIDI and CV together yet, so I have little idea.

To give a bit more context: the Keystep 37 introduced “strum” which plays a ladder of notes (like a harp) when you hold down a single key. My Keystep 37 with the latest firmware does not spit out any usable gate or pitch signal out of the CV outputs

To be honest, one of the main reasons for me to buy the Keystep 37 was this nice generative way of creating sounds, as I have seen in this video (I didn’t know back then that it only works with MIDI, does it?):

I have a keystep pro but i can try and see if i can get it to work, not sure if mine has this strum feature though

I dont think the ksp has that functionality.

I’ll check out some cheap MIDI to CV converter… I already bought sockets and cable. Any recommendations? I guess Arduino is the easiest one.

AO MCVI MIDI to CV

This is a simple MIDI to CV synth module in Kosmo format. Of course there is already the LMNC Midimuso module, but I decided it does more than I need. Mainly I’m using MIDI to plug in a keyboard to a monosynth, so I don’t need six MIDI channels and 18 outputs, and devoting 10 cm of my case to a module I’d only use less than a third of the capability of didn’t seem to make much sense. Hence MCVI (MIDI to CV mark I). It provides pitch and velocity CV, gate, and trigger for Note On events as well …

and maybe also this

#1007 midimuso midi-cv

Right! its on its way, I figured id make the thread! this module took a bit of teething, so I’m sorry for the wait but surprisingly still keeping to a module a month!!! give or take a week here and there. I’m putting together the documentation and videos etc for it today/tomorrow. everything including the listing should be up on Friday. fingers crossed!! it comes with the CV12 chip with slightly modified code including return to bass characteristics, defaulting on the mode 4 channel Mono, and…

Converts MIDI output to CV output from novation circuit or arturia keystep. I am planning to make a stand-alone synthesizer using YAMAHA’s PCM sound source IC, and I had to learn MIDI control for that.

personally in my next box I plan to build the one @analogoutput

[tamasgal]

Yeah the midimuso is an overkill

Thanks @analogoutput I will build that!

Hey, I can confirm that it doesnt work on cv out, which is quite a shame but makes sense if you consider that without the strum you are actually sending polyphonic CVs if that makes sense.
Mine works great now using a simple midi to cv.
Do be careful for the note priority though. I set mine to low and i am pretty happy with it.

I don’t know if you’ll breadboard it and if a stripboard version (not checked yet, but I’m confident and that’s what I’ll do mine with) would help you?

i’ve done this

AO MCVI MIDI to CV

yes allways and for all here’s my stripboard layout, if you see something strange ? it was really not easy and finaly it’s a big stripboard ! [midi 2 cv stripboard by sound bender] btw is there somewhere a better solution to put an arduino in DIYLC ?

[tamasgal]

Thanks, that saves a lot of time! I’ll go with that.

Meanwhile I also create a “feature request”, but I don’t see any chance of a response CC output for strum and similar non-polyphonic features

@Bpbby thanks for confirming. Yes, it only makes partially sense but it would have been nice if they even tried to output something

[TylerTheFolf]

oof…you buy the pro and expect to get all the features :(((

[Caustic]

The pro came out first, so it didn’t have that feature. Might in the future who knows.⊂((・▽・))⊃

[TylerTheFolf]

True true, im still happy with mine anyway
