Title: Newest Prophet Rev2 Main OS - 1.2.0
Post by: Robot Heart on June 15, 2017, 11:18:48 AM

ALWAYS BACKUP YOUR IMPORTANT WORK VIA SYSEX DUMP BEFORE ATTEMPTING ANY OS UPDATES!!
It is highly unlikely to incur data loss from an OS update attempt, but always better safe than sorry. Just remember, you're never going to say to yourself "Man, I wish I'd backed that up before starting..."

The OS can be updated via USB or MIDI DIN.
We do not recommend using the following MIDI interfaces for SysEx transfers as we have had multiple users experience problems with them:
Native Instruments Maschine
Digidesign Mbox/Mbox2
Digidesign 001/002
CME U2MIDI

 Rev2 OS update instructions for Mac or PC (https://www.sequential.com/updating-prophet-rev2-os/)

To check if the OS update was properly installed, go to the Global menu by hitting the 'Global' button. The OS version is displayed in the bottom right corner.

If your OS load countdown doesn't complete:

• Update your MIDI drivers for your MIDI interface to the latest or last known stable version
• Try alternate speed settings: transfer speed settings as low as 25% and as high as 100% have worked for some users when 80% did not
• Try an alternate MIDI interface. The M-Audio MIDI Sport Uno works well here and is relatively cheap
• In Windows with MIDI OX on Windows XP: Try doubling or quadrupling the Size setting to start, and halving/doubling the number of buffers
• Search google and/or forums for the company that produces your MIDI interface to see if other users are having similar problems with SysEx transfers and whether there is a solution specific to your interface
• If you are on Windows XP, try another OS or machine. Although it's not ideal, we have had less problems with Mac OSX and Windows 7. Windows XP has known issues with SysEx transfers

Main OS 1.1.5.9.9

• Bug Fix: Layered gated sequencers offset issue when in key step mode

Main OS 1.1.5.9.7

• Bug Fix: Layered gated sequencers not advancing through steps properly
• Bug Fix: If just Layer A or B is active, the gated sequencer plays all 16 steps in key step mode (arp on/16th), but in stack mode just 8 steps of the sequence are played
• Bug Fix: On the Module, arp relatch does not always work
• Bug Fix: FX doesn't update when changing programs quickly
• Bug Fix: Change master / slave terminology
• Bug Fix: Arp/seq on, sequencer only sends note ons
• Bug Fix: NRPNs still received when Param Rcv global set to OFF or CC

Main OS 1.1.5.9

• Bug Fix: fringe error in oscillator range playback which caused clicks/pops when modulating/triggering oscillator at various frequencies

Main OS 1.1.5.6

• Bug Fix: Improved arp beat sync performance
• Bug Fix: Patch parameters on some presets cause corruption of sound when navigating to other presets
• Bug Fix: Tap Tempo LED does not blink when externally synced
• Bug Fix: Resolved issue with Misc Params menu, encompassing several small fixes
• Bug Fix: Multimode On, single layer prog, select Layer B, PLAY LED not illuminating

Main OS 1.1.5.1

• Bug Fix: Arp beat sync active, first played note incorrect relative to arp mode
• Bug Fix: Improved arp beat sync performance

Main OS 1.1.5

• Bug Fix: With stack active, sequencer triggered by pedal, sequencer does not start
• Bug Fix: Beat Sync improvements/fixes
• Bug Fix: With stack active, synth outputs two MIDI note messages per key played
• Bug Fix: patch parameters on some presets cause corruption of sound when navigating to other presets
• Bug Fix: Stack on, layers set with unique BPM, Layer B tempo indicator blinks irregularly
• Bug Fix: problems with arp relatch in split mode when hold is active

Main OS 1.1.4.27

• Bug Fix: Internal sync, arp beat sync on, arp onset not quantized

Main OS 1.1.4.26

Main OS 1.1.4.25 - Release Candidate

• Feature: Alt. Tuning scales can be exported via sysex from Global menu
• BugFix: Clock synced LFOs were previously being calculated incorrectly, as the result of a bug dating back to the Prophet 08. This was fixed in BETA 1.1.4.18, but resulted in changes to user patches utilizing synced LFOs. 1.1.4.25 introduces versioning so that user patches with clock synced LFOs made prior to 1.1.4.18 mostly sound correct with the fix. The caveat is that some time divisions still won’t sound correct and will need to be manually reset. We felt that is was better to have this bug fixed, despite the inconvenient result in certain limited circumstances. Thanks for understanding.

Beta OS version 1.1.5.9.9 was revved to 1.2.0 for production and is available on the Sequential support page, here:

https://www.sequential.com/updating-prophet-rev2-os/

If you note issues with the oscillators following the update, please calibrate the wheels, clear all calibration data from the synth, and recalibrate the oscillators/filters thereafter.

Calibrate the Wheels: Press the GLOBAL button, navigate to the CALIBRATE WHEELS menu item, and press the WRITE button.  Follow the onscreen instructions to perform the wheel calibration.

Clear Calibration Data: Hold both TRANSPOSE buttons and press the GLOBAL button.  Navigate to the CLEAR CALIBRATION menu item and press the WRITE button.

Calibrate oscillators/filters: Press the GLOBAL button, navigate to the CALIBRATE menu item, press the WRITE button.  The calibration will commence and its progress will be shown on screen.

**If you're updating from below OS 1.1.3, you must:**

Perform a Global Parameters Reset
Recalibrate oscillators/filters

If you are updating from 1.1.3 or above, these steps are not necessary.
