Firmware Loading Instructions
- Download the zip file corresponding to the firmware version you want to install, and put it someplace convenient on your computer, such as the desktop.
- Click open or unzip the zip file to view its contents. It should include these three files:
- “name”.txt (where “name” indicates the version)
- Don’t copy the zip file! Rather, extract or copy the three files in the zip file to the root of the SD card. This is important!
- The card must be formatted as FAT32. It doesn’t matter if there are other files or directories on the card.
- Click open the SD card to view the contents and verify the files are present.
- Power down your ToneDexter by unplugging the power supply from AC line power (rather than by unplugging the power jack on the back of ToneDexter).
- Push the SD card into the slot on the side of ToneDexter, with the card contacts facing down.
- Plug the power supply back into AC line power. When ToneDexter powers up, it looks for the presence of the SD card and reads the files.
- The display will show UPD, and soon after some moving dots to indicate the upgrade is in process. The process will finish automatically and then display the new code version, followed by either:
- GEN (general release)
- HGH (higher pitched instruments like violin, banjo, ukulele, etc
- BAS (acoustic bass)
- Remove the SD card from the slot.
- If you forget to remove the SD card before the next power up, it will unnecessarily go through the upgrade process again at the next power up, but there will be no harm done.
- If you accidentally lose power during the upgrade process, just start the process over and all will be well.
Firmware Release Change Log
Version 1.32 released Feb 14, 2018
- Bass (BAS) version: under some conditions, a fizzy/fuzzy sound appeared on top of low notes. This was caused by the EQ, even when in the off position. Therefore, even WaveMaps created with earlier versions of firmware will be fixed by this release.
- Turning the CHARACTER knob too fast caused the temp display to show a value that didn’t reflect the actual setting. It had no impact on sound. With this fix, all but extreme turning speeds show accurate values.
- Under some conditions turning the CHARACTER caused an unintended very brief temporary display of Bxx.
- Turning the CHARACTER knob while in MUTE/TUNE mode caused an unintended temporary display of “CH2” or other upon returning to RUN mode.
Version 1.30 released Jan 12, 2018
- Blend control. For newly created WaveMaps, character adjustments CH2, CH1, and CH0 are accessible in the right half of CHARACTER knob rotation. When operating in the left half of its rotation, the control allows blending 0% to 70% of the raw pickup signal with 100% to 30% of the WaveMap. The raw pickup signal is polarity and time aligned with the WaveMap so that no comb filtering or weirdness occurs. For existing (legacy) WaveMaps, the blend control works as before with CH0, CH1, CH2 spanning the full rotation range.
- High (HGH) version code now designed for multi-instrumentalists. High bank slots 12-22 use EQ and notch params tailored for mandolin, violin, banjo, etc: low shelf starts at 250Hz, high shelf at 2KHz, notch range is 124 (B2) to 466 (A#4). Low bank slots 1-11 function the same a general (GEN) code: low shelf starts at 125Hz, high shelf at 2KHz, notch range is 73 (D2) to 392 (G4).
- Bass (BAS) version tuner sensitivity greatly improved.
- Level matching algorithm improved for better loudness match between WaveMaps and bypass.
- Paste and Delete function completions now return the user to RUN mode, rather than MUTE/TUNE/EDIT mode. This seems more user friendly and is easier to explain.
- When boost knob adjusted, boost gain did not change until next BOOST activation
- When training with slot 22 (which skips feedback corrections), there was an unintended 3dB drop in level at FREEZE transition.
- Under rare conditions, WaveMap select control could be out of sync (off by one) with knob detent position.
- Under rare conditions, when using feedback notch, it was possible to get into an in-between condition that caused the temporary display to continually retrigger.
- When entering FREEZE mode during training, if CH0 or CH1 selected, extra clicking noise occurred.
- Turning the CHARACTER knob too fast causes the temp display to show a value that doesn’t reflect the actual setting. It has no impact on sound.
- Under some conditions turning the CHARACTER causes an unintended very brief temporary display of Bxx. It has no impact on sound.
- Turning the CHARACTER knob while in MUTE/TUNE mode causes an unintended temporary display of “CH2” upon returning to RUN mode, no matter what the actual CHARACTER mode is. It has no impact on sound.
Version 1.20 released Aug 7, 2017
- WaveMaps created in slot 22 are special in that the corrections to improve feedback immunity are skipped. This results in the most realistic miked sound which may be more useful for recording purposes. These WaveMaps can be pasted into any storage location.
Version 1.10 released May 23, 2017
- 22 WaveMaps – option A/B switch now functions as bank select for WaveMaps 1-11 or 12-22
- Anti-feedback adjustment of WaveMaps improved to have less midrange boost and better level matching.
- The mic path can now be auditioned right after the level setting phase of training, rather than having to wait for the complete training session.
- Temporary display of boost level when adjusting Boost volume control.
- Temporary display of character mode when adjusting Character control.
- Separate HGH (high) code release for banjo, violin, uke, etc. with higher notch frequency range, otherwise the same as GEN (general) code.
- Separate BAS (bass) code release for upright bass. EQ and notch ranges adjusted accordingly. Longer WaveMap length to accommodate lower frequencies.
- Bass WaveMaps exists in separate memory locations and do not interfere with general WaveMaps, so they can coexist in the same box.
- New feedback notch adjustment ranges:
- HGH (high) 124 (B2) to 466 (A#4)
- GEN (general) 73 (D2) to 392 (G4)
- BAS (bass) 37 (D1) to 165 (E3)
- Low level 10KHz noise occurs just when bypassing a slot containing a WaveMap.
- When training from a slot with an existing WaveMap, the first time audition plays S, it plays new WaveMap rather than stored WaveMap. Next and subsequent times through it is correct.
- In audition modes P and M which have EQ disabled, EQ lights were not turned off.
- Intermittent temporary display of notch frequency when knob not fully CCW on some units.
- Temporary display of EQ not working properly in TRAIN mode after training complete but before storing WaveMap.
- Tapping BOOST switch occasionally gives double tap instead of single tap.
- Adjusting Notch control before temporary EQ display times out causes decimal point from EQ to show in Notch display.
