not so much a trick, more of a workaround for the known problem when copying banks into new projects. works only with a second device (digiseries are perfect for this) instead of setting sampleslot-locks on the octatrack sequencer i started triggering sampleslots via slots note mapping (manual page 138). this way i always have the correct trigs via my digitone midi track.

by setting the midi mode mapping to map/track (ot manual page 70/71) you could specify exclusively one or more audiotracks for trigger sampleslots via midi. this makes transferring ot banks and patterns a bit easier as you only have to figure out linking the correct samples to sampleslots after transferring your banks. all samplelocks are done via a digitone/syntakt/digitakt. digi banks and patterns can easily exported as sysex files to maintain redundancy between your digi-device and octatrack.
