I was honored to be asked to open for the Silver Sound Showdown festival at the Brooklyn Bowl this year. It was an amazing experience. I used the following tools:
Thinkpad X60 laptop with a 1.83GHz Core 2 Duo CPU and 2GB RAM. I updated this to Windows 10, but for the month before the show while practicing I wouldn't connect it to the internet. I was afraid I'd get to the venue and it'd start installing updates... Or at bets when it tried to download some it'd interrupt the audio.
Zoom R24 audio interface/control surface
Zoom gave me this one a while back, kindly, and it's really great. My only wish would be that I could use the drum trigger buttons to send MIDI to REAPER... but it works well anyway.
Line6 FBV Express Mk II pedal (you can use this via USB without a Line6 amp)
2x dynamic mics
Home made wood furniture to hold the laptop and audio interface
Electric guitar (direct-in to the Zoom's Hi-Z port)
Flute (amazon $100 special)
House drum kit
I brought my cymbals, but my ride wouldn't fit in my case so I brought the crash to use as a ride, wasn't ideal)
REAPER, Super8 (JSFX), plug-ins
ReaDelay, ReaEQ, various other JSFX, and the classic SimulAnalog JCM900 VST. I also wrote a spectral hold that samples the master output, and another instance which synthesizes from a track with anticipative FX threads, for better performance.
In hindsight I should've used the headphones I had brought for monitoring, rather than the stage monitors, but oh well.
The performance was completely improvised, and while it has quite a few rough spots there are at least a few nice bits in there.
Here's a video (shot with a Contour Roam 2 pointed at my blurred-out crotch, and mixed with the audio recorded by REAPER itself):
Muchas gracias to Silver Sound for having me and to everybody who came out to see the show! Woohoo! Let's not talk about what happened today.
