Thanks for the kind words Sombrero ! I am very glad you enjoy our card - thanks a bunch for your support 😀 I bet since the CS4237 is a PnP chip then your BIOS assumed that the resources you reserved are not for it - but some times PnP is called "Plug n Pray" for a reason 🤣 🤣 🤣

Stop copying others' designs and start thinking. There is nothing extra terrestrial about this LF audio input. And the noise mentioned if not filtered will be present had it been used with a microphone too! The MIC input can be used as line input with just one mere coupling capacitor in series. …

MIC IN is a dedicated microphone input with all parts present on the path as per Crystal design documents. It cannot be used for any other input or switched to something else (to be used as an extra line-in for example, this will not work as copymaker found out)

OK, now it is working MIDI music with unisound! All I did was add 'Blaster= P0' to disable Midiport address(of Crystal chipset). It was suggested by my friend in different internet forum. other Unisound extra setting for Orpheus sound card is only to enable Crystal MPU but there is No disable …

it is indeed the EPM7128STC100 cpld, I have a stock of them left from other projects it worked fine in this case because the port of the original action replay chipset was made with the altera sdk so it was a win-win situation 😁

All my worries were already gone when I received your card. :) Anyway, I deactivated it with the eeprom tool and now it works as I want it to work. Shame is that now you can't add the P330 string to the BLASTER env before running UNISOUND as that will mute the MIDI output. This comes in handy as …

to my understanding /XOM1 is there in case you have CSMPU disabled in eeprom and you want to force using it UNISOUND just looks in pnp eeprom and decides what to activate accordingly so if your card has CSMPU activated in eeprom - unisound will try to use it so I am 99,9% sure if you de-activate …

Thanks for the quick reply! That works. But... my first test was with dosmid which chooses the default mpu from the blaster env. So no sound until I add other runtime parameters to use port 330 instead of 300. This is something I try to avoid. Is there an option to disable the CSMPU like with …

Tried UNISOUND with a Orpheus soundcard with PCMIDI installed (connected to a MP32L). The OPL3/SB part is working great. But when using MIDI (MT32 or soundfont) it sounds weird and also has hanging notes. When using ORPHINIT I don't have this issue. First question is if this combination is …
