Are you saying that this happens *both* on SX600 and SX900 ?
How do you 'continue' the recording from bar 17 - do you set Rec Start to punch in at measure 17? Which tracks are armed for recording on the second pass?
Yes, this happens on both synthesizers, and if such a recording has never been made on the synthesizer, for example, the synthesizer is fresh from the store out of the box, it can record normally several times, a little, two or three times. Then it will already record with a defect. So it’s interesting - is this a widespread defect or only individual copies of synthesizers, for example, for third countries, I have it made in Indonesia, but does anyone have it made in Japan or in some other country?
There are suspicions of a low-quality controller (chip) installed, or a software defect in the firmware of the yamaha. I flashed version 1.10 back - the result is the same. Recording of the whole style plus recording of the 12th channel - guitars for example.
We write 16 measures, then Stop, then we write a couple of measures from the 17th measure as a continuation of the song, it is also desirable to turn on the recording of channel 12 (guitar), in total a song of 19 measures is acceptable. The files are attached above as it is recorded and listened to.
P.S:
All recording options are used, this does not affect the defect. You can write from any measure with any number of recording and playback channels. Even 12 ch wrote on the first ch, CC84 still disappear.
