I am sorry for my mistake. The default configuration is set to WIRE, so it is necessary to change the configuration to SOCKET, as dwestbury said. You can use any C64/C128 related computer. We had the SOCKET as default configuration initially, but later we changed the default, as it could cause conflicts in some particular wire configurations, while WIRE is always ok, just the second SID is not addressed in the second socket. If you make a note while ordering the ARM2SID to you order, I can send the ARM2SID configured as SOCKET.

If you have ARM2SID connected by cable to SID2 and place both to two sockets, it should play stereo the same way as two SIDs. If it does not, then there is something wrong. Was the cable fitted correctly on both sides? Are you able to check configuration in some C64? It should be configured this way by default. Could you give me your order number? I will check it. ARM2SID without cable behaves the same way as ARMSID, it is just a little bit expensive ;-)

NOBOMI reminded me one more feature that can make the second SID (the SID2 socket) play the same music as on the first one. If you do not send any notes to the second SID2 and play only to the first main ARM2SID, it switches itself after 15s to dual mono mode to provide music on both channels, which can make a confusion, that it plays mono. It does not, it just plays the same notes on the second emulated SID.

Hello, it is quite different. If you use ARM2SID with the second SID2 socket, connect it with provided 6 pin wire, and configure it to SOCKET configuration (it is by default) it behaves in 2 SID sockets as 2 SIDs. No doubling the output, ARM2SID has enough processing power so it can process 3 SIDs inside, so in 2 SOCKET configuration it processes both SIDs (the chip select and R/W is brought to the main chip by the wire) and sends the second SID audio back to the SID2 socket by another wire. Thus ARM2SID in socket configuration with SID2 socket and the 6pin wire behaves exactly as 2 ARMSIDs. You can set in configuration one as 8580 and the other one as 6581 or adjust filters and digifix independently. The option on picture that dwestbury published above with directly connected wires is for implementing ARM2SID to C64 or similar and when you provide all the addressing by wires, it does not need any stereo adapter and it supports stereo or 3SID or FM emulation, but it needs the additional wires for addressing. With the 2 SOCKET configuration, it can work only as a stereo, not dual mono as jjonas says. The second SID2 socket provides input and output for the 2nd SID emulation, even it is an empty socket conversion placeholder. Best regards Martin Lukasek ARMSID technical suppot
