« on: August 17, 2016, 05:07:48 PM »
You must install both the Main and Voice OS.

ALWAYS BACKUP YOUR IMPORTANT WORK VIA SYSEX DUMP BEFORE ATTEMPTING ANY OS UPDATES!!
Not that we're expecting bad things to happen, but it's better to be safe than sorry. These OS updates are labelled 'Beta' for a reason; there could be something small that was overlooked that didn't get caught in our testing. Just remember, you're never going to say to yourself "Man, I wish I hadn't backed that up..."

WARNING!!!: There is a bug relating to program loading and combo freezes that only happens in newer units and was due to an undocumented change in our microprocessors in the newer silicon. This has been corrected but a range of serial numbers (approx. 1992-2138) may freeze during the OS update because they don't have the new timing code but do have the newer silicon. In that case you will have to get it manually updated by either sending it to us; please send an email to support@davesmithinstruments.com if this happens to your Tetra so we can arrange to have it repaired

Currently you must update the OS using the hard MIDI IN port, MIDI over USB is not functional yet.

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

If you're on a Mac we recommend using SysEx Librarian to handle the update
To configure SysEx Librarian:
In 'Sysex Librarian->Preferences':
In tab ‘General’ set ‘Pause between played messages’ to 1 second
In tab ‘Transmit Speed’ set speed to 80%
If you have trouble installing, first try setting transmit speed to alternate settings. We have had reports of speeds from 25% to 100% working for some users where 80% failed

If you're on a PC we have had the best luck with SendSX and MIDI-OX. Both are free downloads and work across the Windows line of OS versions.

To configure SendSX:
Install the beta 1.30 version, not the 1.22, to give you more options for speed settings
Make sure 'Split long sys ex messages' is off in the Options menu
In 'Options->Settings' change the speed to ~80% (1.29KB/s works well for us here)
If you have trouble installing, first try setting transmit speed to alternate settings. We have had reports of speeds from 25% to 100% working for some users where 80% failed

To configure MIDI-OX:
Install version 7; version 7.0.0.365 works great here
In View->Sysex then Sysex->’Configure…’
Set the Low Level Output Buffers to Size: 1024 and Num: 1024
Set ‘Delay Between Buffers’ to 375 milliseconds
Check ‘Delay After F7’ and set delay to 1000 Milliseconds

If the OS load countdown freezes before completing you'll need to change the buffer settings and try again
Try doubling or quadrupling the Size setting to start, and halving/doubling the number of buffers
If you experience problems loading the OS and have tried the alternate speed/buffer settings, try the other program. In some instances Send SX works where MIDI OX did not, and vice versa
You should see the display indicate that the OS is being received (if the screen is dark, just move the main volume knob slightly to bring it up). The Voice LEDs will flash once the Main OS is writing to memory. Do NOT turn the unit off while the LEDs are flashing as this could cause a bricked unit.

To check if the OS update was properly installed, power cycle the Tetra. The version of both the Main and Voice OS will be shown on the screen for a short time after powering up the Tetra.

If your OS update failed:
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 1.6.17
Fixed bug: Switching key mode from Normal to Stack/Split not handled correctly when changed on the front panel

Main OS 1.6.16
Added arp relatch global variable
Global can select between normal (same as it works currently, new MIDI notes added to current arp values) or relatch (after releasing all notes, new MIDI notes create a new arp)
NRPN 415 controls global for arp latch mode (0=normal, 1=relatch)
When arp on sustain pedal MIDI now acts as a latch hold toggle
CC#66 now controls arp hold directly (0=arp hold off, 1-127=arp hold on)
Hitting pushit while arp is latched kills playback and turns arp hold off
Fixed bug: Unison bug where releasing the middle note of a chord not behaving correctly in retrigger mode
Fixed bug: Several small bugs when pushit button used in conjunction with external MIDI triggering
Fixed bug: In combo mode, multi off, program volume not display on screen when changing assignable encoder targets
Fixed bug: In combo mode, multi off, master volume pot not handling display and voice select mode correctly
Mopho X4 programs now handled correctly

Main OS 1.6.13
Fixed bug: Sending NRPN 413/414/415/416 caused stuck param behavior where new NRPNs to normal voice params would only update the last received 413/etc
Fixed bug: Combo layer names not updating from program changes when multi mode on

Main OS 1.6.12
Wave reset not responding to incoming NRPNs
Program change added to CC#00 so you can change programs while in combo mode with multi mode on
Bank changes not handled correctly when in program mode with multi on (caused bank 1 to be used even when a new bank was chosen for saves/loads)
Some NRPNs not handled correctly when multi mode on:
NRPN 412: Program/Combo mode query and change
NRPN 413: Voice select
NRPN 414: Get current program on voice
NRPN 415: Get current bank on voice
Changing BPM not refreshing screen correctly
Changing assigned parameter via NRPN could cause crash due to incorrect bounds checks

Main OS 1.6.7b
Added OSC 1 and OSC 2 Wave Reset; control with NRPNs 102 and 103
MIDI Program changes in combo mode while multi is on now change combos rather than the program on the individual voice. Makes more sense this way
NRPN Inc MIDI messages could cause a param to go over the upper bound, this may have been responsible for some unconfirmed MIDI problems
Saving programs in Program Mode while multi is on fixed; initialization was not correct causing saves to the wrong place unless you changed the save location before pressing write

Main OS 1.6.6b
Fixed tuning issue on voice 2

Main OS 1.6.5b
Saving programs now works in program mode while multi is on, you can select the save destination after you press the 'write' button
Added 2 NRPN commands to query the program and bank of a currently selected program when multi mode is on:
Sending NRPN 414 with data 0-3 (corresponding to voices 1-4) returns NRPN 414 with the currently selected program on that voice
Sending NRPN 415 with data 0-3 (corresponding to voices 1-4) returns NRPN 415 with the currently selected bank on that voice
Added response to NRPN 413 to query the current mode of the Tetra:
Sending NRPN 413 with data 0 selects Program Mode
Sending NRPN 413 with data 1 selects Combo Mode
Sending NRPN 413 with data 2 (or any value other than 1 or 0) returns NRPN 413 with either a data of 0 if the Tetra is in Program mode or a dat aof 1 if the Tetra is in Combo mode
Fixed bug: Program changes in multi mode caused bank 1 to be selected
Fixed bug: Voice select NRPN not working correctly in multi mode

Hi

It is great with all the improvements and updates, but why don't you update the user manual so the users can see the right MIDI parameters and settings? It cannot take a very long time to add those small changes when you update the firmware and it is much better / easier to do it when you change the firmware instead of afterwards.

Because this is a beta OS. The user manual is updated only for official OS releases.

You can't save presets with Multi Mode on if you're in Program Mode. Use Combo Mode, which is setup to handle 4 individual programs already.
