I’ve read that this Presonus has big midi latency. Does that interests me with Pianoteq usage? As far as I understand it I will still have to connect piano to directly to computer so there will be no midi signal coming through audio interface in that case?

Please can you guide me what do I need to connect this all? As I can see Presonus Audiobox has midi in and 2 audio jacks out ports. That means I must buy midi cable and converter for those R/L channels to one and converter to minijack port on CA98?

Presonus does not have big latency. Only the PC can produce significant latency.
I have a Presonus. I get 2 msec latency.

As for the connections ...
You said "I must buy midi cable and converter for those R/L channels to one and converter to minijack port on CA98?"

In a word ... NO.
Most modern pianos (including your CA98) have a USB-to-host connection. So you don't need to use the old-school MIDI jacks for a MIDI connection.
Instead use a USB-A to USB-B cable. That's basically your standard printer cable.
Plug one end into the piano's USB-to-host port, and the other end into the PC's USB port.
Whatever you play on the piano will then be available to any suitable software on the PC. You'll just need to configure that software, telling it to use the Kawai MIDI input.
(Notice that the Presonus is not involved in this at all.)

You'll also want to tell the piano software to use the Presonus audio system instead of the PC/Windows default.
Plug the Presonus box into the PC using a standard USB cable. (I think the Presonus box comes with the necessary cable?)

On the PC ... in your piano software's audio settings, choose ASIO mode and Presonus audio.
(The details vary among the various piano software packages.)

Plug the Presonus audio output ports into a sound system.
Those ports are probably 1/4" phone plugs.
You'll need appropriate cables and adapters to suit the connections available on your sound system.

You could use the CA98 as your sound system. I presume it has aux in (or line in) jacks?
If so ... plug the Presonus audio outputs into the piano inputs.

Note: When using the PC to produce piano sounds you'll want to silence the CA98's sound.
Do that by setting LOCAL CONTROL to "OFF". Check the manual to find out how.

Thanks I've been already using CA98 with Pianoteq so I'm not totally green. But with audio interface I wanted to reduce cables. That's why I wanted to plug midi and audio cables(for sound output on CA98) between CA98 and Presonus and then one usb cable from Presonus to PC. Would that work?
As for latency if I'll end up with latency similar to what I have now(1.3 ms) then I will be very happy.

Ok I've bought this Presonus Audiobox 96 and it seems that the problem is still there so now I'm 90% sure it's CA98 problem I'm not sure yet if I'm gonna keep this audio interface in that case. Gonna test further. And I'm gonna get CA98 replacement tomorrow for other reasons so I'll check if the problem is the same there. Anyway latency didn't change at all so I consider it a plus. All went well and audio interface is working ok.

Have you tried recording the hissing and sending the recording to Kawai Tech Support?


Replacement? Egads! You aren't have any luck with pianos, are you starting from Christmas last year!

Not yet,I might. but considering how "fast" they work on problems I don't even have strengh to do this.


Yeah. I just wanted my keyboard regulated and Kawai was "thinking" for over 2 months about that. They exceeded their own time limit so my technician proposed whole instrument replacement which they agreed too.

For comparison purposes, you might want to make at least a cellphone recording before your current piano disappears. Then you can compare it with the replacement to see if there is any change at all, no matter how slight.


The piano manufacturers give you the fastest service don't they? Remind me not to stand too close to you in case it's contagious!

Don't worry, TS. You're under the Yamaha umbrella. (I am too ... for now.)

Ok I didn't expect that but after I got my new CA98 the problem is basicaly gone... There is small hiss when I get closer to top speakers but it's almost unnoticable during normal usage. Soooo I've wasted a lot of time and money because of faulty piano. I can probably return audio interface at least.

Glad to hear that replacement CA98 resolved the issue, and that you received good support from your dealer.

Dissapointing it took such a long time(like I said in another topic) and I did not expect replacement to fix that particular issue but obviously that's a good thing in the end.

Yes, the important point is that this matter has been resolved.

Kind regards,

James, I don't mean to be rude but I wonder if you have this zen attitude when something that you buy and account on takes a long time to be fixed when still under warranty.

Please allow me to answer that question with a little story, which may or may not be true.

A few years ago I bought a new road bike. After a couple of weeks, I noticed a minor clicking sound would sometimes occur when changing into a specific gear, which was a little different to the rest of the gears. That gear still rode perfectly fine, and when cycling normally it was almost impossible to hear or feel any problems. However, I told the bike dealer who said he would raise it with the manufacturer.

A few months later, I heard back from the dealer - he told me that the manufacturer had sent a brand new bike as a replacement. Wow!

Suffice it to say, I was delighted with the support provided by the dealer and the manufacturer.

Kind regards,
James

Except strange sound in gear shift might be a bad assembly and may cause bigger problems and even accident
Anyway in instruments sound problems are SLIGHTLY more important than in "bike".
