Pedal calibration question

Hi,

on first glance that sounds like a bug or defect of the Roland. The inverse scenario can be corrected in Pianoteq, i.e. the pedal not reaching the maximum value of 127 even when it is completely pressed, but this does not seem to be the case here.

If I understand you correctly, the piano already sends CC#64=127 when the pedal is pressed just halfway. (You can verify this also in the MIDI view of Pianoteq, there you see the raw events the software receives.) The problem here is that it seems the piano sends either multiple CC#64=127 events in the 'lower half' or no changes at all; unfortunately in both cases there is absolutely nothing Pianoteq can do about it, since it just does not get the information from the piano.

As I don't know the Roland HP-507, I see three possibilities: (1) maybe the pedal can be calibrated inside the piano's settings; (2) it could be a known problem of the HP-507's MIDI implementation; (3) it could be a broken pedal. I can only suggest to contact Roland support and see if they can help.

I am pretty sure my old Kawai MP6 did have a similar problem. I am also pretty sure in that case it was a design problem, since the MP6's pedal uses an optical sensor if I recall correctly.

This is exact,
I can see the vertical events on Pianoteq's screen in the pedal velocity curve. These events are progressive and continuous but the events come on the right border (max) while my pedal is only half depressed.

I will visit my local piano shop, and see how it works for myself.

Actually, a product like this did exist: the CME GPP-3. However, unfortunately it is seemingly no longer available, and I never saw something like it again. I wouldn't mind having one around myself.

Edit: there is a newer interface that might do the trick, at least for a single half-pedal: http://www.midiexpression.com/

Hi,

personally I think "half-pedalling" in the sense of continuously or repeatedly pressing the pedal halfway is very rare. However, the possibility to lift the dampers slowly is something I actually use in certain pieces, and this requires a continuous pedal; the Casio PX implementation would be useless for that.

No. You press it down a little bit and you get the half pedal effect. You press it down a little more than half way, and it gives the 127 value. It feels like a regular piano, and I don't really notice that I'm not getting the continuous damper.

This is the proprietary 3 pedal board that is an optional accessory with the Casio Privia PX-150 and 350. I'm hoping that Casio comes out with the successor to this line-up, and that it has an improved piano key mechanism (It's great for the price already), variable note-off MIDI messaging, and variable 1/2 damper messaging. I want filet mignon on a MacDonald's budget.
