VH12 configuration

[angr77]

Hi all!

The VH-12 high and low levels seems to be completely weird...could it really differ so much from the VH-11 design? The levels I have got on VH-11 is on low 47 and a high level on about 892 using a 15K resistor and the switch for high impedance set to on...and Altin=disabled. (Without resistor 44 to 192)

Best Regards

Here I got values of:
LowLevel - 303
HiLevel - 885

These seem like reasonable values. Of course you have to set LevelsAuto to No after that and maybe raise LowLevel/lower HiLevel slightly so that MegaDrum reliably registers fully open/close positions.

This set up appears to work but hardly, very short throw of the footpedal.

From my recollection of setting up VH-11, these HiHat controllers require proper hardware adjustment for good open/close range.

Just wanted to note that in MidiLog within Megadrum Manager, when the high hat pedal is depressed, the graph for the HiHat controller is not steady, and bouncing around quite a bit. It actually doesn't reach 0, while fully open does reach 127. Hopefully there isn't a problem with the Hi Hats, as it's very intermittent, but I'm still tweeking things hoping to find a solution.

If it doesn't reach 0 when fully pressed then you have to raise LowLevel until you can reliably reach 0. Of course LevelsAuto must be set to No already. You may also need to raise 'CC RdcLvl'.

Ok. I will double check the settings again and go through the process of trying to get good values. I would like to get this working properly without a resistor but if need be I will try a 15ohm as Anders recommends.

You are right about this. I did set up the hi hat according to Roland specs. The top hat can only go down so far when the pedal is fully depressed. While fully unpressed, is isn't even touching the sensor, and it is fully open. Still a very short throw.

I did find that changing CC RdcLvl to 3 did make a substantial improvement over the jumping of the CC4 bar graph in MidiLog. I feel if the value was able to go higher than 3, it would fix the issue. Off to testing now... Thanks

Hi!

I have also the same feeling regarding the cc RdcLvl ...I was not satisfied with the feeling until I found that setting it to 3 made the trick (on the VH-11.)

If there is this feeling about RdcLvl, I will increase reduction strength corresponding to each of RdcLvl in the next firmware version.

Been trying different things here, and the best result I have gotten is adding a 100k resistor to tip and ring. This is giving me the best range from fully open to fully closed. The Hi Hat graph is still bouncing around like crazy making the sounds unusable.

LoLevel - 423
HiLevel - 522...

very narrow I see, but it's working better than any other way so far.

If there is this feeling about RdcLvl, I will increase reduction strength corresponding to each of RdcLvl in the next firmware version.

I think that might help...

If you do end up adding a resistor then you'd better reduce it to 10-20k - MegaDrum itself already pulls tip(signal) to ring(power) with an internal ~100k resistor.

Something is not right if the range shorter then when without the resistor.

Dmitri,

I've removed the resistor and there is a 10k in line between tip and ring now. I'm not positive but need to know, you built my rack for me... is the hi impedence switch on when it is up or down?

[dmitri]

Up position - Low impedance input (AltIn No)
Down position - High impedance input (AltIn Yes)

So maybe this feature was supported since I asked to this some times before. (probably @dmitri remember to this)

Changes in version 20110816:
1. Added an option in HiHat pedal configuration: 'CC RdcLvl' - CC MIDI messages reduction level . If set above 0 it reduces amount of CC MIDI messages for pedal position changes. Can be set between 0 (default - no reduction) and 3 (maximum reduction).

Instead selectable four steps (0-1-2-3) it would be better to have full range settings from 0 to 127. Value 0 means no Controller Data reduction will be done and value 127 means no HiHat Controller Data will be sending to USB/Midi port. With this functionality everybody can individualize his own reduction level for his own well being inside from value 0 to 127.

@dmitri what do you think about this feature? Thank you very much
