Greg 62.31.73.233 gdavis1@blueyonder.co.uk Keyboard calibration Hi, I'm having problems re-calibrating the velocity on my MPS keyboard. At the moment, even what I'd consider a fairly light touch is giving velocity levels of 110+. Obviously, this makes it a little difficult to play with any kind of expression. I've tried to re-calibrate the keyboard from within the master edit menu, but no matter how hard or soft I touch the keyboard, I just get "bad calibration" messages. Any ideas, or does this sound like a fault? Thanks! Greg Kevin Saturna 216.26.32.85 saturna@efn.org Re: Keyboard calibration Hi Greg, It's nice that the MPS is so straightforward but there are times like this that you can wish it gave you a little more information to work with. :? I've never personally encountered this problem with my MPS+. This sounds initially to me to be a some kind of failure with your keybed velocity sensor. I have a couple of ideas that may or may not be of some kind of help. First, silly as I feel even mentioning it, check to make sure you are hitting the key softly when it asks for minimum and hit it hard when it asks for maximum. Occasionally people can accidentally reverse the process which results in an error. Secondly you may experiment with the velocity curves setting. There is a good range of curves available, moreso than say my KORG Triton, so you might find that it solves or at least helps compensate a little. Thirdly, if you're not too bad with electronics, you might open it up and check the connections between the keybed mechanism and the motherboard, make sure everything is clean and tidy in there, etc. Ultimately if it is an unreconcileable hardware fault then it is most likely in the keybed velocity sensor mechanism and not in the motherboard circuitry itself. That's a good thing because the motherboard is the most unique part of the keyboard and is therefore more difficult and costly to fix, if not impossible. Please post back in the forum to say how things work out, if this helps, or if you find your own diagnosis or cure. ...And maybe someone else has some hands-on experience or insight into this issue. (hint, hint folks! ;) ) ---Kevin randy.B 68.164.41.68 randy.blakely@att.net Re: Keyboard calibration I experienced this when I first got my MPS (used, may 02) and discovered it was because I had the pressure threshhold too low. Temporarily increase your key pressure to a firm setting, then recal your velocity. randy.B Scott B 66.214.86.50 brysonphoto@aol.com Re: Keyboard calibration To recalibrate the MPS: * Hold 'Master' and 'Preset' buttons down while powering up. * Dial up to '6 AD Calibrate' * Press 'Enter' * Press 'Master' * Screen will read 'Clear Cals' - answer yes (Enter) * Move the 'Volume' slider full maximum and minimum a couple times - Do the same with the 'Mod Wheel', 'Pitch Wheel', and volume pedal if you have one. * Press 'Master' * Turn MPS off * Power-up normally. (this was from another website--haven't tried it, but suggest backing up any custom patches--I've heard you can restore factory presets from copying 400-499 but haven't confirmed) Scott B 66.214.86.50 brysonphoto@aol.com Re: Keyboard calibration I noticed this warning under a Reinitialize function that uses the same procedure: NOTE: There are destructive tests in this menu designed for production testing. EMU recommends you do not try these tests. Doing so may render the unit unusable.
