Features/Improvements for OS disk 2.49

DISK DRIVE
  • The COPY FLOPPY utility on the EDIT/System page has been fixed.
  • Removable SCSI drives are no longer surveyed like the internal floppy drive for disk (cartridge) being changed. Since the disk change status will be saved for a SCSI device, changing the disk (cartridge) will still be handled correctly. This prevents MIDI communication problems from occurring when the EPS is being controlled by an external sequencer.
  • In previous versions, loading banks repeatedly from SCSI drives could cause the system to behave unpredictably. This has been fixed in the current version.
  • When resaving a multi-disk sound, it was possible to end up with part one saved twice, thereby making it impossible to reload. This has been fixed.
MIDI
  • Inbound controller #70 (patch select) messages are now handled correctly in MULTI mode. In version 2.40, patch select buttons which were pressed via MIDI were impossible to clear except by rebooting the EPS.
  • There was a bug in previous versions which caused the machine to behave unpredictably when files were loaded via MIDI commands AFTER a bank load. This has been fixed.
DISPLAY
  • The PAGE words in the display again indicate the file type during load operations. This function had been disabled in version 2.40.
SEQUENCER
  • In previous versions, the QUANTIZE operation could move notes near the end of a sequence to the last clock, rather than quantizing them to the nearest note. Sometimes, these notes were not heard. This has been fixed.
  • There was a bug which made it possible for a SONG file to use much more memory than it actually needed. This has been fixed.
  • In SONG mode, a newly-recorded song track played back out of time while auditioning, but was OK after a KEEP NEW. This has been fixed so that the track plays correctly in audition.


Note:

  • Fully verified before shipping and professionally packaged in anti-static material.
  • This Firmware eprom will not work for EPS-M [Latest here is called 2.41]
