iorobyy Posted December 31, 2012 Report Share Posted December 31, 2012 Hello I’m Rob from Venice – Italy and i’m a synth and audio stuffs Diyer. Well after midibox sid and fm now i’m building a diy like-mb808 drumachine but there are a lot of infos in ucapps and in 808 doug site .....i’ve mixed all and now i’m little confused. I’ve built all the ucapps hardware modules bought from smash tv : core with 18-620 pic , 2x din , 2 x dout. I’ve flashed code “setup_808_with_swingpot†and all is working , i’ve connected all dins, buttons are ok But now i’m wiring the dout and i’m a little confused about shift registers outs. I hope someone could help me : First question : where i take trigger signals for instruments? (the 16 step-leds are also triggers out?) Second question : i think i’ve flashed the wrong firmware version for my hardware what are the differences about versions in “midibox_808_v1_3a†pack? someone have a correct pin list for dout pins with “setup_808_with_swingpot†and showtech modules? sorry for the confusion--- brain sssstormiiinggg!! Thanks a lot Rob Quote Link to comment Share on other sites More sharing options...
TK. Posted December 31, 2012 Report Share Posted December 31, 2012 Hi Rob, First question : where i take trigger signals for instruments? (the 16 step-leds are also triggers out?) Have a look into the setup_mb808_default.asm file (which is also referenced by setup_808_with_swingpot.asm) ; Following table allows you to define ; - the track names (must consist of exactly 6 characters!) ; - the DOUT shift registers (SR) to which the drum triggers are connected ; (1-16; 0 disables assignment) ; - the DOUT pin to which the drum triggers are connected (0-7) ; Note: since version v1.3 the "real" Dx pin number (D0..D7) has to be specified, in previous releases it was mirrored! ; - the MIDI output port (0=disabled, 1=Default, 2=Internal, 3=IIC1, 4=IIC2, 5=IIC3, 6=IIC4, 7=Trigger Only) ; - the AOUT/CV channel to output velocity (1-16, 0=disabled) ; Note: AOUT module only supports 8 highres channels, but CV outputs can also be realized with DOUTs (see DEFAULT_CV_DOUT* option) DEFAULT_TRKINFO MACRO ;; Name SR Pin MPort AChn db "BD ", 1, 6, 1, 0 ; Track 1 db "SD ", 1, 5, 1, 0 ; Track 2 db "LT/LC ", 1, 4, 1, 0 ; Track 3 db "MT/MC ", 1, 3, 1, 0 ; Track 4 db "HT/HC ", 1, 2, 1, 0 ; Track 5 db "CP ", 1, 1, 1, 0 ; Track 6 db "MA ", 1, 0, 1, 0 ; Track 7 db "RS/CL ", 4, 7, 1, 0 ; Track 8 db "CB ", 4, 6, 1, 0 ; Track 9 db "CY ", 4, 4, 1, 0 ; Track 10 db "OH ", 4, 3, 1, 0 ; Track 11 db "CH ", 4, 2, 1, 0 ; Track 12 db "Ext1 ", 0, 0, 1, 0 ; Track 13 db "Ext2 ", 0, 0, 1, 0 ; Track 14 db "Ext3 ", 0, 0, 1, 0 ; Track 15 db "Acc. ", 7, 0, 7, 0 ; Track 16 ENDM this is also the place, where you could change the pinning - the .asm file has to be recompiled to a new .hex with the MIOS8 toolchain as described here: http://www.midibox.org/dokuwiki/doku.php?id=windows_toolchain_quickstart Second question : i think i’ve flashed the wrong firmware version for my hardware what are the differences about versions in “midibox_808_v1_3a†pack? someone have a correct pin list for dout pins with “setup_808_with_swingpot†and showtech modules? the complete configuration is described (and can be customized) in the .asm files Best Regards, Thorsten.
