| - | DSEQ32 (aka yet another TR clone) | ||
| - | is based on the classic TR drumsequencers\\ | ||
| - | see [[trsequencer]] for more drumsequencer designs | ||

| - | ====== Features ====== | ||
| - | |||
| - | * 32 step 8 track drum seq, each step has trig/acc/roll | ||

| - | * 8 banks of 16 patterns | ||
| - | * patterns are saved on a bankstick | ||
| - | * settings are stored on internal eeprom | ||
| - | * song mode | ||
| - | * all functions can be executed while running | ||
| - | * forward/backward playing direction | ||
| - | * 24 PPQ resolution | ||

| - | * sysex functionality | ||
| - | |||

| - | ====== Software ====== | ||
| - | |||

| - | |||
| - | * the [[www.doxygen.org|doxygen]] generated documentation is available [[http://webs.hogent.be/~032573mh/midibox/dseq32/doc|here]] | ||
| - | |||
| - | |||
| - | ====== Hardware ====== | ||
| - | |||
| - | Components: | ||
| - | * CORE module [[http://www.ucapps.de/mbhp_core.html|CORE Module]] <sup>uCApps</sup> | ||
| - | * DOUTX3 [[http://www.ucapps.de/mbhp_dout.html|DOUT Module]] <sup>uCApps</sup> | ||

| - | * BANKSTICK [[http://www.ucapps.de/mbhp_bankstick.html|BANKSTICK Module]] <sup>uCApps</sup> | ||
| - | |||
| - | |||
| - | The leds/buttons are wired in a matrix configuration | ||
| - | to reduce the number of DIN/DOUT modules needed | ||
