Asio4allV2 provides much better latency than Motu drivers

[doudou]

I have a Motu Audio Express soundcard for my Acer laptop (Core2Duo 2ghz),
I bought it only for my use of the Ivory II Grand pianos Vst. No complaint about the sound quality, which is better than the laptop phones out.

But for my live piano playing with Ivory, I want a latency as low as possible, I'm very sensible to the delay between the note played and its sound.
The best latency I can run Ivory with the Motu is about 5ms (512 buffers at 96khz), with rare crackles/noises/glitches. If I set the frequency at 44 or 48khz, I can't obtain less than 10 ms latency without big sound problems.

So for testing I tried playing Ivory with the laptop sound chipset and Asio4allv2, and could play it at 128 buffers or less without any problem, with a latency about 3 ms and less, which is much better for me, the sound is more connected with my playing.

precision : this isn't a problem of hard disk (big samples libraries are demanding) because I have a very fast ssd. Apart the buffer, I use the same settings with Motu or Asio4allv2 in Ivory (polyphony, una corda samples, memory use etc).


I'm wondering why Motu doesn't deliver a better driver for our soundcards, capable of ultra low latency settings like Asio4allv2 ?

So nobody can tell why Motu isn't able to give us a driver as good as the free Asio4allv2 ?

Also there isn't much buffers choice with Motu drivers : only 128, 256, 512, 1024 when Asio4all provides much more : 160, 190 etc...

This isn't a company-run board. I would imagine that of your question is not rhetorical, that only a programmer at MOTU could answer that for you.

On the Mac side, the drivers are very solid even at buffers of 128 @ 44k.

ok, I hope programmers will read the post and develop better drivers on the latency side.

Perhaps my future computer will be a Mac, I haven't problems with my PC but it seems like Mac are better for music apps, with Motu hardware...
I'll add that I bought a firewire interface on pc card, with Texas Instrument chipset, the Motu audioexpress functionned very bad (possible only at 44khz, many blue screens etc.), so I use it on usb.
