I have done the following test using the internal sequencer of the Tyros.
I decided to make a simple test. I recorded a song using a fairly complicated style to see if there was indeed any limit to how many notes could be recorded on the tyros to the user memory. I used the “BeBop” style with its amazing 32 bar long section, played various phrases of voices R1, R2 and R3 simultaneously, added multipads, fills, intros, you name it!! Incidentally the tyros doesn’t even flinch despite enormous “payloads” I put on it! By the time I reached 690 bars I was getting a bit tired, so I let the tyros carry on playing and made a coffee… Anyway I finished at about 1300 bars, I noticed though that the main display “bar” counter goes back to 0 once it reaches bar 999 and then counts up again… I saved the song to the user memory with a filesize of 261KB, smaller than expected… so I took it into a sequencer to count the total events as 36,152.. Didn’t think this was enough for a test so I went back and created another song, this time using the casatschock and big band samba styles which contains many notes per bar, and recorded at 227 bpm a very long and intense midifile! After about 1500 bars I received a “memory full” error and the tyros stopped recording, so I attempted to save what I had recorded and analyse it. 345,831 bytes long was the file, Cakewalk reported 53,756 events in total.
I figured out that when recording a song, the tyros does not record directly to flash memory, but to a separate area of RAM. Once you finish recording, you then need to save the song to the user flash memory. The song recording ram is obviously limited to about 350KB, I assume this is quicker and volatile memory compared with the flash memory.
