OK Dan, Rick, any other "Musers"....
Have you personally tried Ivory, and how does it work on Receptor?
Latency? Full libraries or lite?
Do tell!!!!!!!

I played it for 5 minutes, so I cannot tell a lot. There are still some bugs, but the really good news is that we were playing with 32 sample buffers and there was no glitch. We did not push it to the limits, so it may not work at 32 samples if you play lots of notes. Still it is very efficient. And it sounds fantastic.

This begs the question: what are the bugs like?
Before I go plunk the $329 down on Ivory....which I indeed covet, I need some first hand info.
i guess I'll wait a spell.

Thanks for responding so quickly, Dan.

When I say that there are bugs I mean we will have to fix these bugs first, so you cannot get Ivory today. After we fix all the bugs we can fix, if there are other minor bugs that we cannot fix we will list them. Most of the current bugs seem easily fixable.

Already some more news on this? I found that latencies above 3-4 ms are unacceptable to me for playing piano. The sole reason for me not buying receptor was that I never read a post where someone was able to get a 'giga' piano to work at a buffer size of 32 (3.4ms according to the measurements on this site). If you guys can make Ivory work flawlessly at this buffer size (maybe upgrade Receptor with a faster CPU???) I'm sold

I think Giga pianos with buffer size 32 is impossible, at least with current hardware. 3.4 ms latency is extremly little, most hardware synts have much more this (at least that´s what I´ve heard). Actually sound travels about a meter on this time if my calculations are correct (math class was long ago...)! A couple of weeks ago I let my girlfriend make a "buffer size blind test" - change the buffer size on my Receptor like 10 times and I played the same , pretty rhythmic, piano patterns and guessed what the buffer size was (pretty geeky I know

). The results were not what I thought, it was very hard to tell the difference up to size 128 and I even thought 256 was 128 two times. Everybody is different, but I don´t think anybody can tell the difference between 32 and 64.

EDIT: I love to hear something about Ivory on Receptor though!

Well, I didn't want to admit this, but I tried a similar geeky thing

, using a delay effect on my S90, blindly pressing the effect bypass button several times. I could tell the difference when the delay was at 4ms. I then really felt disconnected to the sound (through a pair of Genelics, 2 feet away). My brother, also a keyboard player, had the same problem when latency was about 4 ms or more. Maybe it is a genetic disorder

, but I hope that the Musemen will be able to achieve the 3.4ms with Ivory. At least they will be able to sell another 2 receptors

.

This test probably gave you a latency of about 8 ms.
The S90 already has a latency of something like 3 or 4 ms without the delay effect. So if you add to that.....

I suppose you mean the measured latency between midi out and audio out for the first note? I didn't expect such a high latency from a hardware synth. Time to go shopping...

Bumping for an Ivory update...

We keep going back and forth with Synthogy. They keep fixing the problems we find, but it is not working yet. I wish I could tell you when it will be done, but I don't know.

Thanks, Dan!!

Ivory's working pretty amazing on my Mac. The main issue I run into is the slow disk warning, so I'm considering an external SATA Disk Raid when they're available for my machine.... When Muse get's Ivory and UniWire working it will be time to consider getting one....
