Hi Shakeel. First of all, my apologies for my delayed response. As Mario guessed, I was out of town yesterday gigging and only now finally have the chance to respond. Mario is absolutely correct
. The PSR2000 allows you to re-record accompaniment tracks in 'punch' mode. I'm rather surprised to hear you say that the PSR9000 doesn't support this, cause I thought it did.
The PSR2000 records each accompaniment part (bass, rhythm, chord, etc) to different sequencer tracks (channels). When you want to re-record or replace an accompaniment style (via punch record), you must remember to arm (set into record mode) 'all' tracks (channels) associated with the new replacement accompaniment style, as well as delete the tracks (channels) contained in the orignal style, but not used in the replacement one. Hope this helps. - Scott
