SY Manager MIDI Troubleshooter
At some time or another you are likely to have problems getting SY Manager to "talk" to your synth.
This is a non-branded, low cost, Chinese made, MIDI cable usually found on E-Bay or Amazon. Unfortunately such devices either won't work at all with SYM or will only handle short MIDI messages like Notes.
SYM exchanges much longer blocks of data (sysex) with your synth which these devices can't handle due to various hardware problems - see this thread for more detail.
Note also that these devices rely on the so-called Class Compliant MIDI software driver which is part of Windows. Unfortunately the driver is not actually compliant with the official MIDI specification in that it limits the size of sysex messages to 255 bytes. Since the SY77/SY99 send sysex much longer than 255 bytes, SYM uses larger buffers to manage incoming sysex.
In summary, avoid cheap MIDI cable devices and spend a little more to get a reliable, branded, device that will have its own fully compliant driver.
Check that your MIDI devices are correctly installed.
"I can select MIDI devices when SY Manager starts but then get an error message: SY Manager is getting no response from your synth.."
Assuming your synth is turned on and your MIDI devices are working OK, there are two possible reasons why SY Manager can't communicate with your synth:
Possible Cause 1: Your MIDI cables are incorrectly patched.
Check that the MIDI cable connected to the MIDI Output socket on your PC is connected to the MIDI In on your synth and vica versa.
Possible Cause 2: Device Number set to OFF
SY Manager detects your SYnth by sending test messages on each of the 16 possible device channels (the channel number on which your SY will accept incoming sysex messages). If your SYnth's device number is set to OFF detection will fail. The Device Number can only be switched on from the SYnth's front panel.
To check this setting :
"I've tried all the above but still can't get SYM to work with my synth"
Most MIDI problems fall into one of the two categories above or are caused by faulty MIDI hardware setups.
If you are certain your hardware setup is OK and you still cannot complete SY Manager's initialisation procedure:
If either MIDI input or output messages are not showing then check your MIDI devices are correctly installed as described above.
If both MIDI input and output are working OK but you still can't send or receive sysex messages, then the most likely cause is a problem with the software drivers for your MIDI device or the device itself.
In particular some early drivers for USB and Firewire devices can corrupt sysex data and you may receive a shorter message than SY Manager expects. If this happens check you have the latest drivers for your device.
