Q: I'm trying to play sounds on mt32-pi in MT-32 mode using my MIDI keyboard controller but I'm not hearing anything - what's wrong?
A: Your keyboard is probably sending note data on channel 1, but by default, on power-up the MT-32 is set to receive on MIDI channels 2-10. Check your keyboard's documentation to see if you can change the transmit channel. If this isn't possible, see this wiki page for more information on how to reassign the emulated MT-32's channels.
Q: I'm getting sound distortion and/or the power LED on my Raspberry Pi is blinking - why?
A: It's possible that the Pi is not receiving enough power. When an undervoltage situation is detected, the Pi's firmware can throttle the CPU, causing sound distortion (buffer underruns). Try swapping the USB cable being used to power the Pi, or try another power supply. Check the Raspberry Pi power supply page for recommended power supply specifications.
Q: I'm using a MiSTer interface PCB with a USB A-A cable and the OLED display is scrambled/the OSD controls don't work/audio is distorted - what's wrong?
A: Your cable is probably too long and the IΒ²C and/or IΒ²S signals are being degraded. Please try a short cable as explained in this section of the MiSTer wiki page.
Q: Why don't I see any video output on my HDMI-connected monitor or television? Has the Pi has failed to boot?
A: This is completely normal - mt32-pi is designed to run headless and therefore there is no video output. For troubleshooting purposes, it's possible to compile mt32-pi with HDMI debug logs enabled, but these builds will hang on a Raspberry Pi 4 if no HDMI display is attached due to a quirk of the Pi 4 and Circle. Hence, for regular use, video output is disabled.
Q: What does the Japanese writing say in the logo?
A: It says γγγ’γ‘γΏγ«γ·γ³γ»γ΅γ€γΆγΌγ·γΉγγ γ, which reads as "beametaru shinsesaizΔ shisutemu", or "baremetal synthesizer system" in English.
Q: What happened to the old mt32-pi project that was based on a minimal Linux distro built with Buildroot?
A: That's been archived in the old-buildroot branch.
