Hi Sylphyo Friends, this is my configuration with mini UPS and Soundbank for the front pocket, works fine, sounds fine and I never had problems with it.
I did paid 350 Euro for the Ketron and 50 for the UPS. It can be charged in the car.

And there is still place for a clear sounding soundbar in the bag.

The Ketron has 290 Orchestral Sounds, 292 GM sounds and also Efects:
Multi DSP effects
Reverb
Chorus
Delay
Distortion
Rotor slow/fast
If somebody knows how I can use them please write me.

Best regards!

Thanks for your answers they helped a lot, | have the Ketron SD2 module now and it works perfect, plug and play.

@doul Are the Sylphyo movements up and down, compass ans so on also working with the Ketron?
Do I need to change the CC11 or do any setting to begin with the Ketron, sorry I am a beginner.

Ketron SD2
Hi, I decided to bay a Ketron SD2 looking on the posts in the Forum, but how exactly works?

1. Connecting using which cable , MIDI out from Sylphyo Receiver to MIDI IN on Ketron?
2. How do I change the sound on the Ketron, directly on the Sylphyo?
3. Do I need to somehow preprogram the channels on the Ketron on the PC first to have the first 16 I want for the Sylphyo first?
4. Do I change the Bank on Ketron using the Programm on the Sylphyo
   Thanks and best Regards!
