I’m not sure the foot pedal on my unit is functioning to its full potential. For example with my MF-101, with the cutoff set to 250 and the footpedal heel position at 0, I would expect that the toe position of 4095 should be enough to act as though I’d turned the cutoff control up to max… however it only sounds as though i’ve turned the cutoff up about 75%. That seems a very short sweep for an expression pedal. In fact my EP-2 allows a further sweep.
Also, when selecting heel and toe positions for a setting, I enter edit mode as always, select heel, move the pedal forwards to the desired start point and save it. then after exiting edit mode, I pull the pedal back to heel position (which should now be set to the value of the pedals last location) and the sound moves lower than the value I just selected. Surely the first time you pull the footpedal back from where you set the heel value to it should not change at all?
Sorry if this is rambling!
When I go to footpedal calibration in the utilities mode and rock the pedal back and forth it displays the heel value as 385 and the toe value as 3880 (rather than 0 − 4095), doe this mean that anything above and below those values has no effect? If so, how do you calibrate the footpedal to run the full 0 to 4095?
The MF-101 Filter Cutoff input is set so that it only sweeps ~50% as much as the knob. Originally when we designed it - we thought a lot of guitar players would be using it and the musical bandwidth of the typical guitar signal is less than the full sweep of the VCF. so we limited the expression input so that it could be used more like a typical “Wah” sweep. So what you experienced is normal, and you found a workaround - feed the Cutoff control w/ a bi-polar CV (+/-). In general on current Moog gear (except for the MF104, MF105) frequency related control inputs do respond to negative CVs fairly well.
As far as viewing the pedal range in the calibration mode - a less than full sweep is perfectly normal - and that’s what calibration is for - it maps the existing sweep to the full range.
As far as the editing the heel value - I confirmed that can happen on a unit here - but it stopped doing that when I calibrated the footpedal. Make sure when you calibrate the footpedal that you’re not smashing it down in the heel or toe position or you’ll never be able to get the full range. If you have display units set to “precision” you can verify the real range of your pedal.
Great stuff. The work around is perfect and as for not seeing a full range in calibration mode makes sense. Still struggling with the heel though.
If I edit a patch, allow the heel value robbed altered, move the pedal to where I want the heel to be, in this case the read out says it’s at 750, click the scroll wheel so the heel still says 750 and save the preset. At this point the pedal is slightly forward (as it was moved to the position of 750 in order to save that value to heel… So in theory if I rock it back to the actual heel position the tempo should not change… But it does, it drops way below the 750 threshold I set.
If I go back into the edit mode, the heel still claims it’s 750, edit the patch and move the pedal forwards to 750 again and I get the tempo I had thought was 750.
Seems the footpedal is not actually reading the heel setting when you come out of editing it.
I suddenly have a serious problem. After working fine the gas-pedal is not working any more. Calibrating is failing as both positions are giving 0. Please help. I installed version 2.1/349
I tried now several options, and I am indeed afraid that the LED is not functioning, unfortunately. I ordered an new one and once it has been received and tested I will put another posting. Meanwhile all suggestions are welcome.
I have contacted Moog, and they told me that I could send it to their Tech department, however transport costs are extremely high. There must be a simple solution to check if the LED is working or not, or if there is another error in the system. Anyhow will continue in my search and hopefully it will be working soon again.
Problem was that I could not recalibrate the ‘gas–pedal’. One of the possibilities was the small board containing the LED. The other was a failing ‘movable-mirror’. When I received my (used) pedal it was not properly working and I had to refasten the ‘movable-mirror’. Perhaps I connected it to close to the small PCB board with the led and after a few days of using it, the ‘gas-pedal’ did not worked any more. CALIBRATION also failed and I could choose between 0000 and 0000.
I found a company where I could order a new set (mirror and PCB 11-701) at http://instrumentalparts.com/. I installed it and everything is working fine again. Hope this help others.
