Hi, I want to build a Midibox Sequencer, and i'm just wondering if I got everything right to order. First i ran throught the Hardware-Questions listed on http://www.ucapps.de/midibox_seq_options.html Then i wrote down what i need. Hope someone of you cann tell me if i got everything right. --Pots or Encoders? Pots, because I've 64 laying around here somewhere *g* --How many buttons? 44 as on mbseq Vintage ---------------------- 16 for the steps 04 All, Layer A,B,C 04 Left, Right, Select, Exit 04 Track 1-4 04 Solo, Menu, Stop, Play 04 Metronome, Forward, Rewind, Pause 04 Edit, Mute, Pattern, Song 04 F1, F2, F3, F4 Question1 ??? ? Seem to be useles with Pots ? 02 Scrub, fast and J5? ? ? Does That mean I could add another 16 buttons, and use them to ? send Midisignals (Like Pattern mute and unmute for my MC303 ? perhaps?) ??? --How many LEDs? 79 (with Beat Indicator) ------------------------ 16 Buttons 48 aditional for the other parts 03 Layer A, B, C 01 Beat Indicator 04 Track 1-4 02 All, Fast 02 Solo, Mute 03 Edit, Song, Pattern -- Which display size? 2 2x40 LCD, since there is no way to display the Data on 4 2x20 LCD or even 16 2x4 Question2 ??? ? Does anyone know round displays? I want to have the Displays ? like a Circle. The best Solution for me would be 16 2x4 Displays ? ;-) ? But a round display would also work. Has anyone seen something ? like this? Or is it possible to use four 2x20 displays perhaps? ? ??? --Left/Right button or Datawheel? Left/Right button --Banksticks 2 Bankstick should work.
