Problems trying to run ILectric Piano, iPolysix and Alchemy

The main problem is that iLectric and iPolysix apps both listen on fixed MIDI channels on each and every MIDI source on your device and nothing can change that behaviour. iElectric on channel 1 and iPolysix on channels 1-6.

To make these two co-exist you have to forego the first channel (SYNTH1) in iPolysix. Just mute that channel in iPolysix' mixer.

Now all events on channel 1 will go to iLectric, and channels 2-6 to the various iPolysix voices.

Alchemy's MIDI is a lot more flexible. You can tell it to listen only to the channels and devices you want it to listen to. I'd suggest setting it to channel 7 to avoid conflicting with the other two apps.

To switch between the various synths you can change the channel on the controller you are using.

Note that if you are trying to use MidiBridge to remap notes or the like that both iLectric and iPolysix will still listen to the original MIDI events coming from the controller as well as the remapped versions. To counteract this, you need to set your controller to (for example) channel 8 and then in MidiBridge remap back to channel 1 (or 2 etc) after any mapping using Stream Byter or Note Splitter modules.

That's the gist of the issues with those apps. If you need further help on this it would be best if you could describe your setup in further detail and what you are trying to do. That way I might have a better idea of the best strategy for you and give you some step-by-step instructions.
