This page is al about my TR909 looking sequencer. As soon as I have finished the sequencer based on the V4Seq with LPC board I will update this wiki page.
I have the first PCB's at home for a beta test.
For now you can check how it is going with the projecton at: http://synthage.com/
you can contact me on: http://www.synthage.com/contact/default.html
The MB909 control surface is using the LPC core and altered SeqV4 firmware. currently the sequencer has 2 MIDI IN and 2 MIDI OUT, but this is expandable to 4 IN and 4 OUT. The current LPC core board does not have the extra MIDI's on board.
A three digit led display shows the BPM like on the original TR-909. The BPM is controlled with an encoder. A nice dogm graphical display is used as LCD
The patterns can be for example 32 steps long with 3 trigger layers (gate, accent, roll, ….) and 2 parameter layers(velocity, roll, roll2, …)
