Re: Custom-built multi-bank Roland M-256/M-512 memory cards

And to be fair: - Their cartridge must be containing a much bigger MRAM chip, holding 256 banks (assuming M64C is 8KB, that would be a 2MB MRAM chip compared to our 512KB). The MRAM chip is the single most expensive component in our design, so it must be a big factor in their pricing as well. - The ...

Re: Custom-built multi-bank Roland M-256/M-512 memory cards

So Akai also used the M16C/M64C format in their synths?

Re: Custom-built multi-bank Roland M-256/M-512 memory cards

Just found your site = what an amazing project! Such a shame that you have no stock though. Are you aware of anywhere else doing this (seems like a dead cert for someone in Shenzhen?!) Yes, there are definitely other people exploring this space, but so far noone else is making M256/M512 replacement...

Re: Custom-built multi-bank Roland M-256/M-512 memory cards

Signing up to our list doesn't mean that you commit to any purchase; you will simply be notified when the cards will be available. So there is nothing wrong with signing up and still looking for someone else selling their card at the same time.

Re: Balanced outputs - how to find out?

Yeah, it's definitely not optimal, but at reasonable (TM) levels it doesn't really seem to be an issue. Eventually I may replace those Behringers with more expensive units - now that I know that they do solve my issue, it's a no-brainer to spend more money on those boxes. But for their price, the Be...

Re: Service Manuals and Schematics!

While I found the service manual for the Korg X5D, does someone know if there is a separate one for the X5DR (rack version of the X5D)?

Re: Balanced outputs - how to find out?

Okay, so I had time for one short quick test to confirm something I experienced during an earlier recording. Here's a sine sweep at three different input levels, the last one being slightly above 0dB on the mixer output: https://sagagames.de/stuff/with_behringer.flac https://sagagames.de/stuff/witho...

Re: Balanced outputs - how to find out?

Interesting article. I'll see if I can do some more extensive tests when I find the time - as said, when I played some samples through my XV-5080, they sounded pretty much identical to the WAV file on the PC, but I also didn't try to play them at extraordinarily low or high volumes. I always try to ...

Re: Balanced outputs - how to find out?

Hmm, no idea. My unit is used but since the rest of the sound is okay, I doubt it's defective. My levels are not high. They are always below 0dB on the mixers when playing something, and obviously when just monitoring the noise they are at around -100dB. Here is a direct comparison of the same signa...

Re: Balanced outputs - how to find out?

Good question. Maybe there's some circuitry related to compensating for some drop-off in the treble frequencies? My first thought was noise shaping like it's used for dithering, but I guess that doesn't really apply in the analog domain - and in particular the noise sounds louder than it should with...

Re: Balanced outputs - how to find out?

Got the ART DTI now as well. Compared to the Behringer, the noise floor is definitely less flat - the treble is greatly boosted - but I think the impact on the rest of the signal is marginal, if there is one at all. Still, I think I'd rather go with the Behringer from what I have seen so far.

Re: Balanced outputs - how to find out?

I can't notice any colourization, and the levels also seem to be the same as before. Tomorrow or Monday I'll also have an ART DTI arriving - I actually have two mixers daisy-chained and there is still some hum between those two (but thankfully no EMI), so I will have the DTI hopefully salvage that c...

Re: Balanced outputs - how to find out?

Great news - just adding the HD400 between the mixer and audio interface got rid of the interference. The SNR is now significantly higher. Just recording silence from the mixer gives me about -100dB. Of course as soon as I enable some of its channels they add more noise, but it's a lot more manageab...

Re: Balanced outputs - how to find out?

Hmm... maybe the synths are the least of the problems. I captured some noise before and after turning the mixer on: mixer off/on comparison This is obviously heavily amplified but you can hear the main noise that annoys me, it's 1 kHz + overtones, and it's already there when the mixer is turned off....
