 Home made prototype, finishing now 14th of February 2012 (and it works!!!)

 As soon as I have finished the sequencer based on the V4Seq with LPC board I will update this wiki page.
-I am now in the final stage of designing the board, I have all the parts, LPC board.
+I have the first PCB's at home for a beta test.
-I just need to make one PCB to make sure that everything is working.
 For now you can check how it is going with the projecton at: [[http://synthage.com/]]

 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, ...)
 In edit screen:
-  * pushing one of the 16 general purpose buttons sets the selected step to normal velocity, pushing it again sets the selected step to accented.
+  * pushing one of the 16 general purpose buttons sets the selected step to normal velocity and the led will be orange, pushing it again sets the selected step to accented and the led will be red.
