This pertains to MZ-X500 and PX-560M as they share a very similar control interface, but possibly also other CASIO keyboards. I have an analog pedal on Pedal 2 and the pedal configured to control the Expression parameter for Upper 2 and Lower 2 from min 0 to max 127. This works quite nicely to bring in the second layers gradually. At the same time I would also like to fade out the Upper 1 and Lower 1 layers, so that at the pedal's mid point is where all layers play full. My attempt at this was to use the config "2" of the Pedal Edit to control the Expression parameter for Upper 1 and Lower 1 from min 127 to max 0. This achieves to a degree what I want, but both configurations work linear across the pedal's range, and the mid point (Expression approx. 63 on each layer) has overall lower volume than at the pedal end points where each layer has 127 or 0 expression, respectively. I can limit the range of the expression parameter to not start at 0, but that just means I can't mute the layer completely at 0 or full pedal. Is there a way to make a pedal edit to where the expression parameter stays at 127 from 0 pedal to about half way and then go linear 127 to 0 from mid-pedal to full pedal? And of course the opposite for the pedal's configuration 2? I would expect this would give the proper overall volume across the pedal's range but I can't figure out where I might be able to set this curve up. Any ideas?

Any news yet whether SP-33 and SP-34 are electrically the same? I'd rather get a SP-34 and crimp or splice a PX-560M 5-pin pedal plug onto its cable rather than buy another SP-33 and having to figure out how to trim its crossbar in a way that lets me screw or zip-tie it to a universal keyboard stand such as our K&M 18800.

M-Audio EX-P seems to work well. From feedback I have been reading in other threads, the PX-560M is just a tad sensitive near the low end of the pedal range and velocities tend to come in a bit abruptly which hopefully gets further improved in the firmware.

Try one of these retailers in neighboring Poland; they carry the MZ-X500 for PLN 3400 ~ € 780. https://geizhals.eu/casio-mz-x500-a1548868.html

I'm also using the MGEAR EX-P pedal. Switching between M-AUDIO and OTHER and recalibrating makes almost no difference. I find that either the cut-in from 0 to minimal expression volume is too abrupt, and on other occasions I can't seem to fade it back to 0. I do need to point out that this pedal (like most others) has a minimum limiter dial. I have only attempted calibration with this dial in minimum position and haven't tried calibration of the full expression range with this dial set to any higher value.

Only just picked up a store display model PX-560M with stand and pedals yesterday for 950 and spent about an hour checking out the sounds. Seems like the Hex Layer category has a number of useful worship sounds out of the box. I will continue to play around with delay effects and the arpeggiator, there seems endless potential. Trying to make a Hillsong-style synth that pulses chords at a 1/8 beat, to perhaps place into the Lower 2 layer, to fade in with one of the control knobs or expression rocker pedal.

Would anyone here know if perhaps a CASIO SP-34 could be used with a PX-560 if I replace the round plug with the (SP-33) flat type; or are the pedals themselves electrically incompatible?

Glad to hear the recommendation. I do have that EX-P hooked up to my Alesis VX49 where it works as intended, and I will give it a try on my PX-560M. If it works great I might just spend another whopping € 15.30 at Thomann and get one more for the Casio. I tried my other pedal, a Zoom FP02M, which is a no go. Seems highly logarithmic in response and useless with this instrument. Almost like an on/off switch rather than a smooth expression range.

Well I tried my Zoom FP02M and that's definitely no good with the PX-560M. Probably because it's logarithmic and its impedance is much higher than the manual recommended models. The volume cuts in very abruptly when increasing the pedal just past the first few millimeters, and the rest of the range makes almost no difference. I will give my M-Audio EX-P a try and see if that works well. Supposedly it's linear and near the right impedance range. It works well on my Alesis keyboard controller and is quite affordable.
