Wow… 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.

Stand by for a product announcement in the next couple of weeks. We have a very affordable Meeblip programmer waiting in the wings.

Almost. 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.

Hi 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:

The 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 [...]

The 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 [...]

Dearest Hai Qiao, it would give me immeasurable pleasure to hear that your testicles have been ripped off in a freak scooter accident with a herd or rampaging yaks. 

It will give me even more pleasure once we migrate off this platform.

Excellent news. Have fun with it!

The LED is controlled by software, so it lights up when the microcontroller is running. The first thing to check is that the MeeBlip is set to receive on the same channel as your keyboard is sending data on: To set the receive channel on the MeeBlip SE, press and release the MIDI button. The [...]

The 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. 

Software: 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.

yeah, facing you with the three pins on the bottom.

Well. The forum software mangled that.
