Rastaman! Rockers! I have not forgotten the Teenage Engineering EP-40 Riddim.
While messing with construction kits (again), I got frustrated with the on-line EP-40 guide. Like many people, I want a guide on my own machine, preferably in PDF. Even better, a guide on paper right next to the Riddim.
Necessity is the mother of invention. I rolled up my sleeves and created six PDFs. Each PDF concentrates on a particular aspect of the EP-40. The on-line guide has sooo much white space, I managed to pack a lot of detail into each PDF by squeezing it down. I swizzled the on-line guide to focus on layering and playing loops, and the Supertone synth. If I get into beat making with the EP-40, I will make more PDFS about sequencing.
I’m sharing these PDFs:
- Getting started (plus tempo and time)
- Sound editing (including sample play mode and time stretch)
- Effects (per-group and master compressor)
- Supertone synth (plus Live State and fader)
- MAIN mode and SONG mode
- KEYS mode (including velocity sensitivity and scale)
These PDFs are not comprehensive, so please do not give up on the on-line EP-40 guide. As I said above, they won’t give you much help sequencing or using MIDI/SYNC, for example.
Now the somewhat disappointing news. I created the PDFs from screenshots, not text. Thus, the PDFs are not searchable. I opted for more PDFs with at most two pages per file. You should be able to narrow your interest to a particular PDF and should be able to scan quickly through its two pages. Sorry ’bout the lack of text search.
All of the PDFs display text and diagrams on a solid white background. I tried to make the text and diagrams as readable as possible on paper when printed.
The EP-40 OS 2.5 update adds several substantial features.
- USB audio
- Reversing samples
- Selectable sampling rate (26,250Hz, 32,000Hz, 46,875Hz)
- Longer MONO samples (up to 40 seconds)
- Equal length AUTOCHOP
- Arpeggio (one-shot or legato type samples)
Working with Yamaha SEQTRAK and Teenage Engineering Riddim, wow, they are very different machines. Unless you intend to buy both, choose wisely, padawan.
