1. NEW FEATURES :
1.1 : New FX Type : SAMPLE RATE REDUCER (SRR).
The FX TYPE parameter has now 7 settings : Normal, Dual, Disto, Lo-Fi, Reverse, Thru and SRR.
The SRR FX recreates a bug that sometimes appeared after switching BIM on or when tapping a slow tempo.
The DELAY pot controls the sample rate from 20 kHz (DELAY pot at zero) down to 2 kHz (DELAY pot full). The TAP Tempo and MIDI Beat Clock sync are not active when SRR is selected.
1.2 : MIDI CC no. 93 is assigned to the TAP Tempo. The CC value has no effect, each CC no. 93 sent to BIM is equivalent to pressing the TAP switch.
1.3 : You can dim the brightness of the 8 switches.
Press FX TYPE switch while powering BIM on.
The DATA pot now controls the brightness in 4 steps.
When you are ok with the brightness, swicth BIM off and on.
This setting is kept in memory.
The brightness dim function is not applied on the submenus (Active mode, Display mode, …), the Preset save mode and the MIDI menu.
2. IMPROVEMENTS:
2.1 : On previous revisions, when you tap a Tempo on the TAP switch, the Quarter Note was automatically selected. You can deactivate this feature (called «TAP Mode») by pressing TAP and DIVISION switches while powering BIM on.
Each time you press TAP and DIVISION switches while powering BIM on, the «TAP Mode» is alternatively set to ON or OFF. This setting is kept in memory.
2.2 : On previous revisions, unused spaces of RAM memory was not cleared when you change the RANGE setting, when you tap a new tempo or when you load presets.
This can lead to the replay of old sounds (called «ghost sounds») that can be annoying or creative, depending on the situation.
You can now decide to keep these «ghost sounds» or not by pressing DIVISION switch while powering BIM on.
Each time you press the DIVISION switches while powering BIM on, the «Ghost Mode» is alternatively set to ON or OFF. This setting is kept in memory.

Check the serial number on the sticker under BIM: units below 1000 take the revision 1.x file, units 1000 and above take the 2.x file (never install the other one; units below 0300 should contact OTO support first). Download the matching BIM firmware zip from otomachines.com/support/ and unzip the .syx file. Connect your MIDI interface's MIDI Out to the BIM MIDI In. Open SysEx Librarian (Mac; set pause between messages to 250 ms and SysEx receive timeout to 500 ms) or MIDI-OX (Windows) and select the interface. Switch BIM on while holding DIVISION, FX TYPE, FILTERS and OFFSET until these four switches light up, then send the .syx file. The LEDs show the progress and BIM restarts by itself when the update is done.

BUG FIX:
MIDI CC and PGM CHGE messages were not working well under certain circumstances.
Version 1.3 — 1 Apr 2018
1. NEW FEATURES: 1.1 : New FX Types : REVERSE and THRU.
The FX TYPE parameter has now 6 settings : Normal, Dual, Disto, Lo-Fi, Reverse and Thru.
REVERSE simply read the content of the Delay backwards, with short fade-in and fade- out to avoid « click » noises.
THRU let you use the whole BIM circuitry (input gain, filters and 12-bit AD & DA conversion) but without delay. RATE, DEPTH and F-BACK pots are inactive in this mode.
1.2 : TAP DISPLAY : TAP tempo display can be set to ON or OFF.
This setting is accessible by pressing the TAP switch while powering BIM on.
Each time you press the TAP switch while powering BIM on, the TAP display is alternatively set to ON or OFF. This setting is kept in memory.
2. IMPROVEMENTS: Improvement of the accuracy of TAP tempo, MIDI beat clock and FREEZE.
TAP tempo has a better behaviour, the tempo is captured after 2 taps.
The synchronisation of delay times when using MIDI Beat Clock is improved.
Please note that due to the technology used in BIM it’s not possible to get the FREEZE function perfectly synced for a long time.
3. BUG FIXES:
3.1 : AUX mode: Spillover and Aux mode were not working well, especially after changing the ACTIVE mode parameter or after a preset load.
3.2 : The delay time was unstable for a short time after a MIDI stop and play, thus creating some audio artefacts. Now the delay time is not reset after a MIDI Play or Stop.
3.3 : TAP Tempo display was not effective in « TAP to LFO » and « TAP to BOTH » modes.
3.4 : IN GAIN parameter was corrupted after a « TAP to LFO ».
3.5 : « LFO Division » was not working after a change in setting. Needed to tap the tempo again.
