■The EM-1 combines a drum machine and synthesizer with a sequencer: an eight‑part drum machine and a two‑part (mono) synth section all sample-based with sound control, leaving the analogue modelling technology from ER1 with some simple controls like EG. The display is quite simple with characters like from the 80'.

■16‑step, pattern‑based sequence based on classic TRXX with motion recorder.
Each pattern can consist of up to 64 steps which: four bars of 16 steps, no other signature but triplet patterns. Drum parts are programmed by selecting one of the eight drum keys , then using the 16 sequencer keys to assign them to the desired step. Melodic section can be played on the "piano like" section with special glide legato for TB effects and accent. You can chain up  256 patterns in 16 performance songs.

FACTORY RESET: The pattern and song data with which the EM-1 is shipped
from the factory is referred to as the "preloaded data," and
you can restore this preloaded data back into the memory of
the EM-1.
When you do this, the patterns you created and the songs
which use these patterns will be erased, and replaced by the
preloaded data. If you wish to keep the patterns and songs
you created, you must save the data on a data filer etc. before
you load the preloaded data.
1. While simultaneously pressing the Transpose key and the
Write key, turn on the power.
2. The display will indicate "PLd," and the Play/Pause key
will blink.
3. To load the factory preloaded data, press the blinking Play/
Pause key.
This will require apporoximately 30 seconds.
To cancel, press the Stop/Cancel key.
When loading is complete, the EM-1 will return to its initial
state. After several seconds the display will indicate pattern
number "A.01," and the EM-1 will be in Pattern mode
