Distortion when played from a midi keyboard.

Hi

I have been away for awhile from this forum, and from PT.
I have just been refamiliarizing myself with PT and noticed basically the same problem on my system.
It is the main reason I do not use PT, except to play a midi file now and then.

It would be interesting to hear from others who have experienced a similar problem.
Are there any PT/MIDI gurus out there who might have some insight and a possible solution?

I browsed the forum for "distortion" and got a few hits that seem interesting.
This one;
http://www.forum-pianoteq.com/viewtopic.php?id=1188
is from 3 years or so ago, so is based on PTQ 3 (or 3.5) but it seems relevant.
I should AT LEAST twiddle with some off the twiddleable things and thangs therein mentioned and suggested

As a mere "user expectation" I still find it surprising and disappointing that I don't get exactly the same sound from my midi controller as I get from a midi file.
If I accompany a midi file that is playing and has good sound then my accompaniment should have the same sound (voice, or timbre).  Volume may be a different issue, I can play harder or softer, or adjust the velocity curve, but the basic TONE should be a LOT closer than it is, without all the distortion.

I deleted it. Wasn't best put. Here is again and if you don't want it I'll delete again.

Get Elmar GASANOV's MIDIs from DisKlavier Competition 2009 and hear them thru, watching the Pianoteq Velocity telltale meanwhile. He placed nowhere, but stands out from the rest for beauty of touch, and the telltale shows that's likely to be from an unusually wide spread of touches, and changes of spread, at any time. You'd think, on learning a piece his attention would first go to this point, so marked is the difference in his approach.

Why should one expect this instrument to sound all the same, in all circs and with all pairs of hands, when variation of touch is wholly what it's designed to produce? Unless the general approach IS standardised, of course; and that was what the judges were listening for, and best-exhibited wins.

Are you using Windows Audio, Direct Sound or ASIO? An audio interface? Rebuilding your system may help but if you give more details on your setup, maybe someone here can be of more help. But this is probably blatantly obvious...

The problem you describe simply cannot be caused by Pianoteq.  Pianoteq responds to midi events which are described by a few simple parameters like note value, length, velocity.   It will make the same sound whether that midi note comes from a file or a keyboard for the same set of note parameters.   Pianoteq records all the midi sent to it.  Why don't you record some midi from you keyboard and then play that file back in Piantoeq.   The audio would have to sound the same.   If the file you recorded sounds terrible, perhaps you could post it somewhere so others can test it and perhaps figure out what the problem is.  When you say the sound is terrible can you be more specific?   I'm pretty sure the midi display in Pianoteq is specific to Pianoteq and reflects the midi input it is receiving either from a file or from keyboard input.  The only explanation of your situation that I can think of is that your keyboard is sending out bad midi messages (like velocity is always 127 or something).

I might have made a microscopic amount of progress

The File->Audio/Midi setup->MIDI window shows EVERY NOTE played from my keyboard as being received on channel 1 and on channel 2, also their note off messages. 
As to why I didn't notice this before...  maybe I just confirmed that SOMETHING was being received with a note number SOMEWHERE in the low 60s and a velocity around 50, so didn't examine the channel # - OTOH maybe it wasn't there before last night.

I shall track this and hopefully figure out how to set the board to send on only ONE channel.
This does not happen on files played to PTQ from my "background music juke box".
Since the juke box sounds good/fair one might reasonably conclude that the the issue is with the extra notes on channel 2.
 
BTW, that midi window shows what is received, selecting a different channel in the bottom left corner seems to only stop them going to the sound generator of PTQ.
My default on that was "ANY", I have set it to "1" in the hope of filtering out the channel 2 extra notes, but the distortion remains. 
All notes still show, but I get no sound if I select higher channels, e.g. 15.

I will update this thread if/when there is more progress.

Thanks to everyone who has responded.
