Re: MT32-Pi Wavetable Board

Posted on 2023-02-15, 18:29

Okay, build complete and here's the report: Upon doing a test fit the Pi board conflicted with components below the Wavetable header on my non-PnP SB16 and looked to have the same problem with my YMF-719. To fix this I relocated all components except for the passives (caps and resistors) to the …

Is MT32-Pi similar to WavePI ? https://www.vogons.org/viewtopic.php?f=62&t=65908 Not super familiar with that... seems like a more platform agnostic implementation of MUNT and FluidSynth, and the wavetable adapter talks with the host via serial? Basically rather than a bare metal implementation …

I stand corrected. 😅 To elaborate a wee bit, the sound coming from MUNT and FluidSynth is pristine (provided the CPU can keep up with it) but the PWM audio is not great, the DAC uses a completely different path and the chip is basically acting like a sound card - the OS even uses drivers to …

The WP32 McCake does has a DAC - it's a PCM510x chip on the back of the board. So the audio quality would be comparable to the WavetablePi when fitted with the PCM5102 DAC. The analog audio coming in from the wavetable header is essentially another line-in. The quality of that audio certainly does …

How is this different from McCake? EDIT: Pi Zero 2 W? Wavetable Pi has a DAC My bad, they both have a DAC , uses GPIO for accessing the Pi, meaning you're not locked to a Compute Module (or even a Pi, necessarily - if someone ports MT32-Pi to another platform with a Pi style GPIO or an adapter …

I think you are a little confused about the Dreamblaster X2 which certainly doesn't want to emulate an MT-32 device; in the specific case it wants to be a good wavetable able, through special banks, to make the listening experience varied (probably it can simulate a Roland SC-55) 😄 The MT-32 …

MT32-Pi Wavetable Board

Posted on 2023-01-31, 00:56

So I came across this: https://github.com/scrapcomputing/WavetablePi and haven't really seen it around but definitely going to build one. Basically a DIY project that turns a Pi Zero 2 into a Wavetable card running MT32-Pi. For those who don't know, MT32-Pi turns a Pi 3A/B, 4 or Zero 2 into an MT32/ …

You can also mod a PC Engine for c-sync. https://assemblergames.com/threads/pc-engine-core-grafx-rgbamp-csync-csync-tutorial.58933/ I'm a pretty good hand at soldering overall, I did the SNES Jr. RGB mod the old school way, no add-on chip just wires, caps and resistors. (I also modchipped a few …

Re: RGBs to 15KHz VGA?

Posted on 2019-09-10, 10:42

VGA requires H-Sync and V-Sync, so a simple cable won't work. You need a converter. I'd use a cheap GBS 8220, which will also remove the need for a 15 KHz-capable monitor. Alternatively, you could build a Sync Signal Separator like this one. If you are really lucky, though, a 15kHz-capable monitor …

RGBs to 15KHz VGA?

Posted on 2019-09-10, 02:44

I'm having a problem Googling this properly as searching for RGBs to VGA ends up with a mass of craptacular converters. Supposing I have a monitor that supports a standard VGA connector and 15KHz (Dell U2410), how would one convert a 4-RCA cable RGBs signal? Is that just connecting the pins or would …

You can also find DC/DC Converters replacing 7805 for example. I also removed the 7805 from my SB Card and added a DC-DC Module for example. If you have several cards and each one has one of this buggers you can save a little bit of energy, and also reduce heat inside the computer case. i also …
