Experiencing distracting 'beat' or rhythmic change of timbre when a note is held (either manual) using choir or strings stop. It gives the impression of FM generated tones. How else could I describe the effect - when holding the single note on strings for instance, imagine the repeated, quiet chirping of a cricket!
I have to say that the aftertouch on the AT-90 is poor when compared to that of the later Yamaha organs where it adds warmth and breadth to the tone of a cello or trombone etc. This compares with the twanging of an elastic band on the Atelier!
Is this chirping effect appearing when you play towards the top notes of the keyboard?
It's hard to hear what you are referring to otherwise..
It could be nothing more than the loop point of the sample.
As to the aftertouch, didn't know there was a setting for 'rubber band'.
What do you mean when you mean the Yamaha added warmth - I've never seen a 'warmth' setting on anything.
Aftertouch can be assigned to do many things, that said I'm coming from a synth background, so I'm not sure where to point you to change it on your AT-90.
I did look at the specs, 256 tones to play with - crumbs, that's a lot.
More bizarrely, it has a choice of 2 manuals (as in written information - not keys) to download, the American Classic, and Luxury.
The 'chirping' - a far better description than my own wandering terminology, is evident particularly in C1.
Is it the case that Roland instruments ought not to be criticised? If you were to read my post carefully, you would see that I made a subjective remark on the outcome of using the aftertouch (touch tone) facility on a Yamaha: giving warmth and breadth. This subjectivity is one to which I hold.
If you have access to an AT-90 and were to use aftertouch at any greater amplitude than 3, you would indeed experience the waverings of, perhaps a musical saw - once again, an improved description on my original.
Sorry to bewilder..
It's just these beasts are not really my field of expertise. I think that shows.
Well C1 isn't way up on the keyboard, so I can only assume it's the loop point of the sample.
Never having seen or heard the AT in action I can only surmise.
I took the criticism as a problem to be resolved.. You can be a critical, & subjective as you like.
Sadly, no access to the AT so I'm unable to experience the waverings.
It does sound (no pun intended) as if the aftertouch is assigned to the modulation of pitch, with a sin ~ or triangle ^ wave.
I think it's more a case of knowing what Yamaha have done with regard to how they have assigned the aftertouch than anything.
It could be as simple as changing the filter brightness (cutoff), or increasing the amplitude of the signal, or changing the effects parameters (reverb levels / times).
Sadly I very much doubt there will be many AT owners, and users here to help.
I nearly fell off my chair when I wound out how much this thing cost. There's me thinking synthesisers where expensive.
Here's a possible lifeline:

As you can see 'AndyG' has some criticisms too, but he does seem to know his onions (so to speak).
