oh, I dont got a 1000 either
I know the 404 will be fun because the 303 is fun... it's amazing.
it works for live on the fly fx playing... some live sample triggering.. you can play the pads live on the 303 etc... it's good enough for that.
Also, those are great for those times when you aren't making beats but you are working on making new loops and samples to use in future projects...... the fx totally work well for that. super gritty too.
Okay, none of the onboard fx are really a new thing (or any of the features really), but the conglomeration of all those things is what makes the machine totally worth it.
