Today I've detected a bad limitation of the Tyros (flash)memory. I'm happy to own all
the available Premium Packs and Voices of Yamaha. I completely deleted the Custom and Premium Voice Library and formatted the expansion memory to be sure all memory is free. Then I've only loaded all the Yamaha Premium Packs and Voices (PanFlute, Trombone, VintageKeys, Entertainer, Euro&US Organ, Choir&Vocal, MixedChoir, etc, etc).
The following memory status is shown:
A total of 504MB memory is used and 518MB memory is still free.
But take account of the Waveform Counts....it's almost totally used. From the total of 1280 Waveform positions, only 92 are free.
Then I've loaded some Custom Voices, resulting in the following memory status:
Still 364MB of memory free, but only just 28 Waveform positions available. Notice that in proportion to the Premium Voices, the Custom Voices uses way less Waveform positions.
At this point I would like to load some sounds of the Europack. I receive this message on the Tyros 4 display:
Done....I've bought an expensive memory flash module of 1GB, still 364MB free but due to limitations of the Waveform positions I'm finished here. There are 473 Waveform positions needed, but there are only 28 Waveform positions available.
I'm really disappointed by this limitation and will contact Yamaha about this. I hope this can be solved by a firmware update (if it's not hardware related). In this state I (and everyone that also own all the Yamaha Premium Packs and Voices) am not able to load any future Premium Packs or Voices anymore from Yamaha as there are not enough Waveform positions available anymore (even if I don't load any Custom Voices).
