So are you asking how to measure a tiny voltage? Or something else?

I believe you missed myusb.Task() inside your loop() in the "host" code. Also if you could wrap your source code in code tags next time, it would be a lot easier to read.

Weird, yeah don't add a DC offset to any speaker. That's a bad idea.

What do you mean by "ride"?

If you share your code on github or something, it would be a lot easier to offer suggestions. Although, the Linnstrument is really expensive so it might be hard to find people who actually have one to do "real"...

What a cool idea, great job. Never seen the Linnstrument until now. When you say you're looking for help/collaborators, what kind of help do you need?

That was for my envelope code, which has nothing to do with john-mike's code.

Apologies for bumping this old thread, but here is another granular pitch shifter implementation: https://github.com/pichenettes/eurorack/blob/master/clouds/dsp/fx/pitch_shifter.h It blends or interpolates the grains...

Thanks a ton, I will give this chip a try :) It's the cheapest way I've seen thus far to get this many channels.

Hey there, sorry to revive your old thread, I was just curious about your DAC setup. Are you using the PCM1681, did it work straight away in I2S mode? Could you share any more code/info about it? Thanks.

It sounds like you're making a Daisy-style board... very intriguing.

The T4 MM would go into my custom hardware. I want to be able to position the USB host and device connectors and uSD connector wherever I want, and use whichever connector style I want. That can be done now of course,...

True, I had forgotten about the supply strain on the bootloader chips. I suppose there's still hope :)

I didn't anticipate the T4 MicroMod to actually be manufactured by sparkfun. The radio silence since the git commits and blog posts in October could indicate one or both parties lost interest, or maybe SF is just too...

Do you anticipate certain issues due to the density? My eyes are still good enough to solder it.

I really like the idea of a T4 MicroMod and hope that it sees the light of day. :)

Here's how I adapted the Mutable Instruments envelopes to work with the Audio library: https://gist.github.com/wcalvert/2a5b5f1c9d0d4066cab27fa6ac526a60 I started with Pichinette's python code to generate the lookup...

Sounds awesome, great job!

The Audio library is heavily dependent upon the specific microcontrollers that are used in the different 3.x and 4.x boards, and doesn't support any 8 bit chips. The Mozzi project does support 8 bit chips, I've never...
