I am a little late to your question but:

I have several devices connected to my Deluge and let them all play, what the Deluge wants them to play.
Have a Projekt, where my Miniloge XD plays a Lead, Digitone some Chords and Plucks (2 Midi Channels), Crave plays the Bassline and my Blofeld listens on 3 MIDI Channels for a Pad, an Arp Sound and some Effects. Thats 7 MIDI Channels from the Deluge to external machines.

All Synths go into my Mixer. For recording I either play "live" and record it in stereo into a portable Recorder (Tascam DR-40) or I record each Synth on their own into my DAW.

FX Routing is either done in the machines themself (Digitone has Reverb, Delay, Distortion for example) or by external effects routed by the mixer.

If you mean by recording, recording MIDI, you need to think about your workflow. As far as I understand, Deluge is only able to record to the active Track.

If you need a different sequencer, depends on what you want to do. Deluge is capable of a lot of stuff, but cannot do everything. Recording multiple MIDI Sources "at once" is one part it lacks. I personaly like the accessability of the deluge sequencing, but i think there are better devices, if you mostly want to record midi and play it back. Also, you need to programm everything in the deluge, as there is no MIDI FX Section.

What I found out: If you want to setup you Synths in a room, press on Record/Play and run around like crazy Playing all your synths like into a looper, the Pyramid will be the device of choice. From the Videos I have seen, its unbelievable powerfull. I thought about it a lot, but as I a programm/sequence my music instead of playing it on keys into a machine, the Deluge is more for me, than the Pyramid.

Exactly. For Midi-Files I can clone the track, change the midi data, and from that moment on, the patterns mute each other, they appear on the same track in arranger mode etc.
If I clone the audio track, the same happens, but there is a sample on the track that I cannot get rid of.
