Bad timing of notes played with samplers and SDS

[chakrablue]

Hello !

I have following problem : Samples played via MIDI with STS2000P, STS3000 or SDS have a very bad timing. If you play the same track e.g. on the eds8i the timing is perfect, so the problem is not the midi-timing, but (I guess) has something to do with the RAM-Access of the samplers.
The Timing is not overall late, but variies from one event to another.

My PC :

Powerpulsar
Athlon 1000, ASUS A7V133, VIA KT133
384 MB SRAM PC 133
AGP Card, PCI-NIC, Symbios UltraATA100, no Sound Card
Win98SE

I´ve read about the PCI-Problems with VIA KT133 and changed the the latency timer setting in BIOS, but without success.
I tried to change the Chipset-Registers 70 and 75 with WPCREDIT, but the settings were correct in original state. At least I think so, the Arbitration Method Change differs from the description, it can be changed from "Fair arbit.", which is currently set, to "PCI/pri".
I added the lines "[PCI] maxpcichannel=200" in CSET.INI, but without success.
I tried to change the SDRAM-Settings in BIOS from 3T to 2T, but my system did not boot after these changes.
16Bit-Color and USB-Disabling were useless, too.

I experienced not so much problems with the PCI-Overflow-Error, I can run a PulsarMixer, 8 Synths, STS3000, 3 Masterverbs and 3 Delays without much trouble, so maybe the problem is not the chipset, but something else ?

Would be great if anyone has an idea how to solve this...

i saw a new patch out for via boards. it is mainly for better RAID performance but i believe it actually helps the PCI bus.

it may help you.

It helped !!

Grrrrr...I downloaded this patch several days before and DID NOT istall it...my thoughts were "if you add power to RAID, you subtract it from PCI".
Sometimes trying is better then thinking.

Thank you very much !!!
