oder potis bzw buttons, du musst ja irgendwie die noten angeben für den jeweiligen step, oder wie meinst du das ? zitiere: Pots or Encoders? MIDIbox SEQ allows to modify step values with rotary encoders (endless knobs) or pots. Since pot control sounds like "vintage", "old style" and "analog sequencer", and possibly could imply that pots are the best solution for perfect sequences, I want to warn you that this is just a popular fallacy and nothing else! In fact pots are only useful for sequencers which are controlling the analog gear directly, but for a MIDI sequencer you defenitely want to have features like "total recall" and "jumpless switching" between tracks, layers and patterns. Therefore the most prefered option for MIDIbox SEQ should be rotary encoders! There are two reasons why MIDIbox SEQ supports pots: 1) pots were used by the first PIC16F based implementation (MIDIbox SEQ V1) - users who already built this sequencer are able to upgrade to V2 by exchanging the PIC and the crystal in order to benefit from all the new features. 2) users who built the MIDIbox64 hardware are able to upload the MIDIbox SEQ firmware in order to have a lot of additional fun :-) greetz
