Midibox Drum Sequencer

7 posts in this topic

Here is a clip of the Midibox drum Sequencer driving a TR-9090. I have one issue. When in Live mode  most of the drums do not trigger manually. I have a feeling it is because velocity is not being sent as well. Any ideas what I am doing wrong? Thanks!

Finally!!! :)

I will look into the velocity issue soon

The board that I built some years ago is still functional and I typically show it to MIDIbox HQ visitors as one of the unknown projects that the community started but never released :)

Best Regards, Thorsten.

Is there a PCB for this drum sequencer somewhere, or how did you do it? Just the 9090 seq?

This is awesome, I also have a TR9090 set of pcb's.

Doesn't the TR9090 have a midi to trigger that is able to handle velocity?

I mean are you triggering from the sequencer from midi or are you using gates?

Hi there,

It is triggered with a combination of a trigger and an accent. Thorsten changed the firmware so it can provide individual accent levels for each instrument, like the 909. So the sequencer can handle velocity.

As for pcbs I kind of lost my way with this project. I was going to make a few pcbs and make a project out of it but life and other similar looking projects kind of dimmed my motivation to do that. I have eagle files for the pcb if you want them. The firmware obviously here somewhere too.

I would be interested in the eagle files. I have not built a drum machine yet and it would be nice to replace my roland tr8 with something built.

Hello,

I'm interested in the software, I've got a Yocto 1, the bad point with this machine is the low quality pots and the ATmega firmware.
I resolve the pot problem by replacing it by 808 original set, was not easy not the same size at all! But I founda way ;)

Now it remains me to put a good sequencer inside, a MB one ;)

Best
