Record your music and play along to it like a Looper Pedal. The LoopDeLoop recording looper let you record musical parts and then play them repeatedly on a loop that you can play along live too. Enables you to practise playing in a band, or with an orchestra, in a synchronised way. Perfect for sample; practising your guitar (or any other instrument or singing). You put on a simple base line and then play the tune along to it, forcing you to keep up with the rhythm, eliminating the fretting grip pauses, and training you in playing along with others. For the more experienced player it creates the effect of a whole board of Guitar Pedal Loopers, letting you play like a whole band. Will let you record up to 8 different loops for each song/tune (2 in free). And as many songs as you like (10 in free). Each loop can be as long as you like (depending on the free storage space of your device), sample a full verse, making it into a Mini Daw with a recording made up of up to 8 different instruments/voices or a combination. Large record/play/stop button so you can hit it quickly while playing. Takes it's input from default and outputs to default, so if you plug in a mic or headphones, (or a special plug where the mic is your guitar lead and the output goes to the line in on an amp) it will automatically switch to those, just like your phone normally does when you plug in your headset. You can record and rerecord each loop as many times as you like, and create many different songs/tunes with a multitude of loops, so you can store and replay the music at a later time. LoopDeLoop offers stereo/mono recording, selectable SampleRate, Loop naming, loop specific volume control and adjustable loop start synchronisation Recorded files extractable by using a file manager like My Files and accessing: moonc.mobi/loopdeloop (Deleting or editing files may cause LoopDeLoop to error) Extra large record/play button that can be hit in a hurry while playing. Its the next best thing for guitarists to an actual physical footswitch. Multilingual, adjustable to: English, Norwegian, Danish, Swedish, German, French, Italian, Spanish, Portuguese, Dutch, Chinese, Polish, Russian, Japanese, Hindu and Arabic.
