Hi MuShoo, thanks for joining in! I'm on Linux, but apparently there's an equivalent for that. Even a 12 teensy solution could be cheaper than a multichannel soundcard, so I'm giving crazy designs a chance. Anyway, I've been calculating: say I'm using 16bit samples, plus 4 additional bits to...

Ouch, although I was expecting this. So what I'd need is a super fast processor and something like 150 Mbit/sec usb speed, correct me if I'm wrong. If it helps, it's 24 mono channels, not stereo. May I ask - do you guys know of any microcontroller capable of that? Thank you.

Hi wise helping people, I'm building a fretless tapping instrument that has twelve independent strings and I'd like to turn it into a hybrid synth where the twelve inputs would be processed in SuperCollider with an Odroid (or something alike) and then fed back to the strings via independent...

Too late :p I just realized those muxes have an ON resistance of 2.5 ohms, while the ones from TI had around 70 ohms, that might be the reason. However, I bought the muxes already so for this time teensies are coming :)

Thanks Constantin, all my worries solved! I like the idea of using digital pins as address. I'm using 16chan multiplexers already, more specifically the CD74HC4067E from TI, but when one teensy is reading all channels from more than 6 multiplexers you can clearly notice it's scanning slow...

Thank you for your quick responses! I'll take a look into the I2C approach. CAN sounds promising but perhaps too much of a hassle for me. Constantin, when you say a single serial bus - do you mean a setup more or less like the one I described above? If so, is there any significant difference...

Hi, I'm making a musical keyboard using the touchRead() function with some 16channel multiplexers. But it's an awful lot of keys, so, in order to scan them all fast, I need at least 4 teensies. So I thought I could have those 4 scanning and sending the data to a fifth teensy, the one that'd be...

Hi there, I built an isomorphic keyboard (much like the Axis 49) using no more than a Teensy 3.1, a wooden box, metal thumbtacks, copper tape and a bunch of multiplexers. The principle is simple: the tacks nailed to the wooden surface are the keys, each soldered from below to one input of one...

Mmm, those might be interesting. I don't see the problem with it being QFN if it comes in a breakout board. But from the tutorials I have seen (and I might have misunderstood), it looks like it's not sensitive, it only indicates whether it's pressed or not. That's rather sad for a musical keyboard.

Hi there! So I've been trying all possible sensor shapes. In the end, the only thing I found robust enough to feel satisfied was the brute force approach: many electrodes, I'm using thumb tacks actually. It looks more like a keyboard than a multislider now, but of course the proximity of the...

Well, that sounds quite logical, thanks for pointing out. Although there's the Soundplane ( http://madronalabs.com/DIY ), which solves this using carrier stripes if I understood it correctly, but it's a whole new level of complexity. I wonder if it'd be possible instead to use two bobbins...

Hi Pictographer! thank you for your kind answer. But one little problem I have with that geometry is that I'm trying to get the sliders to be 1cm wide and around 40cm long. Fitting two or more triangles there seems nearly impossible. To which I can think of two solutions, tell me if you don't...

Hi there! I was taking a look at the CapSense library on the Arduino Playground and I thought it could be useful for a project of mine, in particular the capacitive sliders. http://playground.arduino.cc/Main/CapacitiveSensor?from=Main.CapSense I'm attempting to build an OSC controller with...

Thanks for reading, Headroom. I'm afraid the noisy thing is unrelated to the code. I thought it could be an interference with the MobilePre USB audio interface I'm using and so I tried uploading different codes (from Examples>), and the result was always the same: while Jack is running with...

Hi there! I'm trying to use the OSC library to send OSC messages to SuperCollider, reading first 24 analog inputs with two multiplexers and then sending them this way: OSCMessage msg("/cuerdas"); msg.add((int32_t)cuerda1); // cuerda1 is one of my analog readings msg.send(SLIPSerial)...
