Modulation via "Touchplates" like Soma PULSAR-23 / MN Strega
Are there any ios apps out there that mimic this feature? Seems perfect for multitouch devices ... being able to (virtually, for ios) send modulation sources to destinations by touching them both at the same time, to let the signal run through your (virtual) body ... could be great for performing.
Bonus points if reacts to "pressure" too! And on ios, could add things like hold, invert, multiple busses, attenuverters, path switches, gates/triggers on touch, etc.
Maybe could be an AUv3 midi device where you route modulators like LFOs from various apps into a set of "touchplates" in this app, and then route another set of touchplates in this app to destinations in other apps? A little effort-heavy to set up that way, I'm sure.
Can you already achieve this in any of the modular apps like Drambo or mirack?

The strega and 0-ctrl sounds good. Wonder if you could get mirack audio out to the strega?
Yeah you can. Any audio. Think it acts like a tape effect.
See the Tact module in miRack for touchplate like CV control. Or for keyboard style MPE touch controller: Mononoke by Bram Bos.
For non-touch modulation, you could use something like Holonic Source module in miRack, and convert gestures to CV/midi. In the video below, I'm using an iPhone to control parameters on Audio Damage Continua and K-Devices Shaper.
Dont know much about cv. Can you sequence a stria from ipad, with a cv connector and send audio from ipad? Just asking. Guess the sound is good. Not even sure what you gain.
Very cool. Thanks for that. I was thinking something like this ...
I personally haven't heard any Strega demos I like. That abrasive wall of noise style just sounds like a half-unplugged cable ran through a cheap delay pedal to me. I prefer the organic, beautiful, emotive side of modular and boutique synths.
With that said, the closest I found to a usable touchplate controller on iOS is with Animoog. There's an IAP to use the app's keyboard as a midi controller. I was able to use the Animoog keyboard with a cheap USB to CV converter, and my little Moog Werkstatt, assigning the Y-axis to modulation of the hardware Moog's filter, which I found to be very expressive. I think you can also assign the mod strips and big TV looking x/y pad to midi CC.
Maybe it might sound cool above a bluetooth keyboard, that is switchable via midi on an ipad. The synth goes through strega. Or not but tuning it as you play keys, then maybe use a looper. I guess you could just tweak an un-sequenced synth.
May aswell just use mononoke.
Thanks! I'm not looking for a "touchplate controller" like that though ... I'm looking to be able to live-route modulation sources to destinations via touch. Pulsar 23 and Strega let you do that by actually allowing you to use your body as a conductor of electricity. I'm wanting to replicate that feature virtually in ios (well, I want someone that actually knows how to program in ios to do it
). Has nothing to do with the sound of Strega and I don't think Mononoke can do this, unless I missed it. Maybe something like it could be programmed in Mozaic though using the pads view ... not sure
This is actually a great idea, it should be doable for binary connections (i.e. not dependent on contact surface, which is what touch plates usually provide). If that's fine with you I could work something out.
Hell yeah!
(By the way, I claim no ownership ... it's just a brain fart. You certainly don't need my blessing to try something!! But thank you!!)
Can this type of controller be created in Lemur or TouchOSC?
I just built something in miRack as a proof of concept using four LFOs. Works pretty well, but lot more work to do. Obviously a little awkward to use
Really like this idea. Not sure the best way to go about it but looking forward to what the forum drums up. MIDI Designer supports at least some of the functionality you're looking for.
I don't think you can get XY info from Mozaic pads. Can the MIDI CCs of the four knobs be changed based on a held pad? If so, you could maybe set Pads 1-4 as sources and Pads 5-8 as destinations. Then you'd hold, say, Pads 1 and 6 and use the upper knobs to set the attenuation of each. I guess you could then use the lower pads (or some SHIFT function?) to cook up some sort of hold mechanism. Or maybe treat the lower two knobs as some sort of hold toggle. I haven't really hacked in Mozaic since launch so take all of this with a monster grain of salt.
Animoog or Rozeta XY or (free!) Midi X Y pad

to hardware?
Also, the Arturia Keystep acts as a midi to cv converter and works with the iPad via CCK. I have one. This is what the blurb says about it:
“ KeyStep features two capacitive touch strips, one providing classic pitch modulation, and the other providing expressive modulation. The modulation strip also provides an additional control voltage via the dedicated ‘Mod’ CV output on the rear - which can also turn key velocity and aftertouch into voltages, too.”
Also - not a controller, but an example of an emulated ‘crackle box’ resistance-triggered style device is this, by the maker of the brilliant Dr. Om https://apps.apple.com/gb/app/dr-om/id555409573 drone box:

Unfortunately, both of these excellent IAA devices have unfixed display issues, and it looks like they are pretty much abandonware at this point.
I created a more elegant version in MiRack using 8 of the Tact modules suggested by auxmux above, only to learn the hard way that MiRack is not multi-touch! ... so can't touch and hold one LFO input and then tap on the outputs to let it pass through. I vaguely remember reading that before, but I forgot! It was looking so good!! Back to the drawing board
@PZoo Just go to the Wrench/Settings and enable Multi-touch in miRack. 😄
Ahahaha - thanks!!!
Nice. Would you share it when you have a chance? Or maybe just another screenshot? Would like to see how you have it all set up. Are you using internal-to-MiRack modulation sources or using Rozeta LFOs->MIDI to CV in MiRack as a source?
Absolutely. Here’s a screenshot for starters. I’m using internal LFOs to test it out. I’d prefer if Tact let you return to zero when you let go ... seems like that works in VCV but not MiRack (but I probably missed that too!!)
In playing around with this a bit a more, I don't think miRack is ideal for this given features of existing modules and the small controls (like the quad VCA faders). Also, even AUv3 in general not ideal to have to bounce between windows (e.g., if use Rozetta for LFOs, this miRack patch to control routing/levels, and then mapping in / watching the target apps). Just wasn't as much "fun" as I'd have hoped. I do think a more streamlined app in the middle could be good, maybe something with wild inter-modulated LFOs built in directly .... but I will go back to my original comment ... I just think it would be a cool feature to build these touchplates from Strega directly into ios sound generating apps so you can easily "play" modulation live like you'd play a virtual keyboard live instead of having to go into mapping windows
Are you wanting audio generation or just a control interface to send to the sound generating software? TC-DATA is an interesting touch-based controller with tons of possibilities. The6 als9 have a synth with the same interface.
Just control data. That is a great idea. I have it but frankly never spent the time learning to program it. Thanks!!
I think TC-DATA or Midi Designer are your ticket. TC-DATA has a bit of learning curve and there is a lot I don’t understand but makes for really powerful touch control.
Thx again. It really is great, but my feeble mind hasnt been able to figure out this particular use case. I think I’ll just have to scrap this use case for a while then!
