Some information about your Tape Loops

Be sure to insert your Tape the correct way into your Player/Recorder -Sticker/Screws side is up

And remember, the nature of these tapes means they are perishable over time so treat them with care when loading them into your machine.

BPM values and calculation

I have found these Bpms work with these Tape lengths. Bear in mind though, each Tape Loop is unique and you’re looking at +/-2-4 bpm depending which division you’re working with. Experiment with your sequencer to get the Loop tight.

Tape length (approx) Ms || main bpm Div / 1    
4.6 secs 4,600ms – 105.4bpm 52.7    
7.7 secs 7,700ms – 124.7bpm 62.35    


Identifying your Tape loop length

A word on erase protection tabs

In order to protect “accidental” recording (aka erasing your masterpiece) all cassettes have a record protection system in place. These are the little tabs on the top of the cassette (left hand side according to the side of the Tape you are working with). If this tab is removed, you will be unable to record on the tape. To overcome this, you will need to cover the tab using either a purpose designed (or 3D printed) insert, or more commonly this is achieved by covering the aperture with a little bit of tape (any tape is fine, just don’t use too much as it may cause problems inserting into your recorder)
