Using Tascam Model 12 with the MPC One

Isn't the buffer setting indicative of the device you're hooked to (for instance, you computer)? You're saying that changing the buffer on your computer for your Model 12 causes a "save-state" in standalone for other USB Class Compliant devices that it's hooked to?? I mean, if that's the case - that's pretty sweet - and a glaring thing that was missed by everyone complaining about pop/click.

I'm not 100% sure, but it seems to me that the buffer size is a setting that's stored on the device. Otherwise I can't explain why it works for me now. Would be great if some of you guys here could test it, I'm very interested to see if it works for someone else.

I have the same issue here.

Here is the demo: https://www.youtube.com/watch?v=gDPPLAj7wlo


Phenomenon:

All the sounds come from Akai MPC One will randomly and frequently trigger the crack sound

What I have tried:

1. Same sample rate (44.1khz) and bit depth (tried 16bits & 24bits)
2. Akai MPC has updated to the latest firmware 2.11.5 & Tascam Model 12 has updated to the latest firmware 1.30 too
3. Tried buffer size 512, and used Windows Tascam Model Mixer software to increase buffer size up to 2048 samples

I have the same issue also
I read somewhere that people got these problems since the firmware 2.11.5. Is someone can confirm ?
Some people tried with the 2.11.6 ? Is it working ?
If not, how do you downgrade to 2.11.4 ? Is it risky ?

Your second issue in that video (when you're using Spotify and then start playing a video from your Photos App) has nothing to do with your MPC or USB Class Compliant audio - that's an issue with iOS/the iPhone and its Lightening-to-Analog adapter. I've had that happen to me before without the MPC or anything.

Anyway, I encourage both you and Romain to try the new 2.11.6 firmware with your Model 12's and see if it's any better...

I unfortunately can confirm that I have the same issue of random glitches running 2.11.6!!
I'm going to downgrade to 2.11.4. By the way, when downgrading the MPC HW, do I need to match the desktop software to the sale version?
Any link to DL both Soft and Firm 2.11.4?

Hope AKAI will fix this ASAP

I also have had to downgrade to 2.11.4 as it is the last Firmware version that the Model 12 works properly.

Nothing special involved in downgrading, but it's a bummer not to be able to try any of the new instruments.

Hopefully they fix this as it doesn't inspire a lot of confidence--two updates (12.11.5 and 2.11.6) that break a heavily advertised feature on the one interface, TASCAM Model 12, that they actually demo the feature on.

Are both of you running at 44.1 Khz and 16-bit on your MPC's? I'd also try hooking your Model 12's up to your computers and raising the buffer setting using Tascam's drivers to see if that addresses your issues.

Thanks for the suggestions.
I have done the buffer setting, that improved things awhile back (2.10 maybe?).
I’m not going to start running sessions at 16 bit when 24 bit works fine up to 2.11.4. The problem is clearly on Akai’s end.
Right now it’s only a mild annoyance, but it would be nice to be able to update and take advantage of new features one of these days.

Just for fun I updated to 2.11.6 again as I had never tried at 16bit. After resetting preferences, and then creating a new 16 bit song on the Tascam, unfortunately, I get the same result: consistent digital artifacts on playback.

Finally I decided to downgrade to 2.11.4. And it works perfectly
My conclusions/tests :
2.11.6: glitches
2.11.5: glitches
2.11.4: OK
I’m currently running MPC 2.11.6 on my laptop (OSX 10.15) along with the MPC Live 2 os 2.11.4 and I didn’t face any incompatibilités for now.
Hope this helps

Thank you! This appears to work perfectly for me too.

Interestingly, the official MPC One page's big red 'download' new firmware button right at the top of the page downloads the 2.11.4 firmware, not the 2.11.6 version. Guessing Akai are well aware of the issue and promoting 2.11.4 as the more reliable firmware for now.

New 2.11.8 update fixed my audio issues with the Model 12!! Can’t express how happy I am.

it fixed the issue for standalone mode but now it cracks and pops in controller mode.
