A très bientôt donc.

From what you record, it seems that bank messages are sent by your software. Question remaining is whether the SD1000 is actually listening from such message coming to its DIN MIDI Input or only from the USB/MIDI interface.

I tried to check the behavior of the EWI but as I "only" have EWI 4000 and EWI USB which do not handle bank select message (the EWI USB even do not send any program change message), I couldn't get to any conclusion. If you could check with a MIDI monitor software what is sent by the EWI5000 when sending prog change, this could help us.
Having the program change from the Sylphyo working with the VL70m is not really a surprise for us as this one is our favorite hardware test synth.

Fine, then we will investigate next week the differences in the MIDI sent by the EWI and the Sylphyo and check what is missing for the specific use with the SD1000. And adapt the Sylphyo behavior to match the EWI behavior regarding Prog Change sending (my assumption is that the SD1000 is waiting for a bank select message before the program change message but I do not have an EWI at home - Sylphyo only).

I found other people having trouble to get program change working using the non-USB DIN MIDI In on the SD1000 though it worked perfectly with the SD2:
How to test sound module on computer? (win7).

I need to try to test my Ketron SD1000 sound module because there is a problem when I connect it up via MIDI cable.

I have 2 Ketron modules:
The SD2 which works perfectly.
The SD1000 which is faulty when its connected up with the same cables and Midi ports I used to connect up the SD2.Why does 1 Ketron module work properly and the other ketron module doesnt work properly."

You should be able to select sound from Voice Bank A using program change sent by the Sylphyo (we do not send bank selection message yet, as we are trying to think about a smart way to handle such a huge bank selection possibility in a user friendly way, rather than just scrolling from 128 Prog Change with 128x128 bank to select from). Question is: does it work when you directly connect the EWI5000 MIDI OUT (DIN) to the SD1000 MIDI IN (DIN) without any PC connected ?
If so, this would mean it is possible to get the program change from a MIDI controller to the SD1000 MIDI In working, so we should find a way to upgrade the Sylphyo firmware to make it work.
When you say "direct Sylphyo-Ketron connection", you mean Sylphyo MIDI out receiver powered with the charger connected to the SD1000 MIDI In (with no computer) ?
When you say "Sylphyo-receiver-PC, with receiver-Ketron" do you have the same MIDI cable from the receiver MIDI Out to the SD1000 MIDI In and the receiver powered by the PC ?
Can you play the default piano sound in both case ?

One extra question: could you describe a bit more your setup and wiring ? PC on the way or direct standard DIN MIDI connection from the Sylphyo MIDI receiver to the SD1000 ? If you know a place where one can find the SD1000 MIDI implementation chart this could also help us to understand the problem.

One more question, what Sylphyo firmware revision are you using so that we can load the same for testing purpose

Hi Wlodzislaw,

Using the SD1000 should be straightforward. We never had the chance to test this configuration yet.
This is quite strange as we are using regulary MIDI Program Change when using hardware synth.
If you can successfully play the Piano sound from the Sylphyo, this means that the MIDI connexion is OK. Are you using your PC Win 10 between the Sylphyo receiver and the SD1000 ? I will check the Ketron MIDI implementation chart to try to understand why this doesn't work. Is this working when using the EWI5000 instead of the Sylphyo ?

Thank you for this feedback
Providing custom fingering edition is on our Todo list. Meanwhile we would keep on checking user suggestions and check how we can integrate them into the forthcoming firmware upgrades.

Serial number can be found on the sticker above the on/off switch (AS0xxxx).
