Advice on live set (software/hardware)

This kind of thing is really simple to do with ableton live, you would probably be able to even manage with the intro version for your needs. You can even keep the same pedalboard interface should you so wish.

Im working on a similar set in live suite, where a keyboard has the songs start as scenes ( a live term that plays a combination of audio and midi clips at the same tme) and then a switch can advance in time to the next section when I want to. This way I can have group of clips together and have songs end, then have live bridges that I play myself in the middle and then one click and im into the next section (or song). Live also does all the preset management of my external gear, and routes my midi keyboard or guitar to whatever instrument I want to play live.

you only need a mixer if you plan to play stuff to the pa besides the ableton live output and beyond using the soundcards inputs as a mixer. With the alesis you can use its two inputs to mix a two mono inputs alongside the stereo mix of your ableton live tracks and send the whole thing in stereo to the clubs pa. You can also go mono and send them two separate mono signals, say mixed chip to one channel and synthesizers to another, which makes things much more flexible with your bands monitor mix.

For example you might want to send mixed everything in mono to the pa, and only the chiptune rhythm sounds to your drummer for his monitor so he can keep time easily.

yea live can be a real life saver, although there are a few other products out there that can do it as well, there much more help on getting it done in live.

ps: your band sounds cool too!

It doesn't seem, that drummer have to use a click. I think famitracker wavs are good for him enough. but if he wants it, the solution depends on your soundcard (number of outputs). if you have only stereo output, you have to send famitracker to one (left), click to the other (right) and you will lose stereo panning (if you like to use it). So, with the click, you can record click in the same tempo, as famitracker wavs and then play these two simultaneously by mapping them to same midi note, maybee. or you can learn how to create music in ableton (and create it with a click here).
But I play C64 in my band, sending it to mixer, then to PA and with aux output of the mixer I am sending it to drummer's right headphone. He plays according to this. And he has monitor with my C64 and other instruments and voice from the left side. I think it's usable this way. without click.

every drummer is different, at least the run of 6-7 I ran with in 2005-7 where. Plus you wrote the songs, so that may be a factor in anticipating the song on some level. For us, some needed an isolated click, some where great off the mix, some where terrible no matter what (but still great drummers outside the box!). The nice thing about ableton is its really made for live control, and the more you can do by not touching a computer the greater a crowd will be convinced that its all you up there, and you arent playing to a cd or something. You can even get into live effects of your stems or other such creativity as the songs get developed.

That's very true. I'm not saying Ableton is to be avoided, just that there are easier and cheaper ways to do basic playback, even multichannel (to make room for a click) than ableton. If you really want to get into live fx, dynamic roadmaps and the like, that's a whole other ballgame worth the investment.
