I liked J4T Multitrack Recorder. Unfortunately, it doesn't have a piano roll or drum loops, and it only has four tracks. I think you can bounce and import to one track when you need more, though. I didn't really go beyond recording some voice overdubs, but I know it has basic effects, looping, and editing.
This is the exact predicament that convinced me to switch to the iPhone. It's hard to compete with apps like Notion, GarageBand, Music Memos, and the Positive Grid stuff.
I have used this app in the past J4T Multitrack Recorder but the quality is pretty meh... I recommend getting a cheap laptop with line-in and a DAW to get some decent audio quality
I use it every time I need to record and edit on the fly Simply amazing and updated all the time Brilliant DEV
I use J4T to record ideas and stuff. It's a simple 4 track recorder for android. Works really well as a quick demo/audio sketchbook tool.
There's a multitrack app I've used called J4T. I forget the price, but it was pretty inexpensive. You can listen to what you've recorded using headphones while recording additional tracks. The weak point, though, may be your phone's microphone.
