MeeBlip: 14 minutes ago · ViewWow… C’est un travail incroyable. We apologize for encouraging you to spray plastic chips all over the living room carpet. ;)
The 500mA power supply should be more than good enough to drive the Micro (which requires < 100mA) and the Novation together.

MeeBlip: 1 day, 21 hours ago · ViewAlmost. The sample is a 16-bit word. One channel gets the most significant byte and the other gets the least significant byte. Then they’re summed.
I’ve got a spreadsheet with the actual measured values somewhere.

MeeBlip: 1 day, 23 hours ago · ViewHi Stan – I think it’s time for me to adjust the pitch bend to something slightly more desirable.
MeeBlip responds to the mod wheel, as long as the LFO is turned on. Every other parameter is MIDI controllable, too. See the MIDI CC list at the bottom of this page:

MeeBlip: 3 days, 7 hours ago · ViewThe dual op amp is simply a 4-pole low pass filter. The two 8-bit outputs from the DAC are passed through two different value resistors. By summing the output from the two outputs, you end up with a higher resolution waveform. It’s not as accurate as a proper 16-bit DAC, but it’s far better than [...]

A goal of the MeeBlip project is not only making our hardware open, but being open about what we learn making that hardware. We tended to keep some of that to ourselves at first, but now that we have something more meaningful to share, we’ll be a bit less shy. Getting things rolling, MeeBlip’s chief engineer [...] -

MeeBlip: 5 days, 6 hours ago · ViewThe oscillators are stored as 24-bit ramps (sawtooth waves). To generate a tone, the software simply adds a 24-bit delta (value change) to the ramp. There are two oscillators, and the values are stored in the following variables: ; increase phase for DCO A DELTAA_0: .byte 1 DELTAA_1: .byte 1 DELTAA_2: .byte 1 ; increase [...]

MeeBlip: 1 week, 1 day ago · ViewThe DAC outputs are weighted – one channel is the highest 8 bits, the other the lowest. It’s a rough approximation, but it works rather well. It’s a parallel chip that’sflit banged 2 bytes sequentially for each sample.

MeeBlip: 1 week, 2 days ago · ViewSoftware: You’d have to set up a software PWM output that toggles the LED on/off to vary brightness.
You could configure an LED on the audio output as a sort of simple VU meter. It’s analog, so should be relatively straight-forward.
