42. ACCENT
1 SH-1oh1
The SH-1oh1 is a MIDI retrofit and feature extension for the Roland SH-
101 synthesizer. This manual only describes the features that differ from
those of the original SH-101. Great care has been taken to avoid altering
the original behavior of the synth while only adding features on top.
2 Accent
While the siblings of the SH-101 – the MC-202 and TB-303 – both have
this feature, which is important to many musical styles, it was unfortunately
lacking in the SH-101. . . until now!
The SH-1oh1 accent consists of an envelope with a fixed fast attack and a
decay adjustable between one millisecond and five seconds. It can be routed
to the VCA, filter or both while the amount can be adjusted individually.
The accent can be programmed in the sequencer or triggered via MIDI
velocity in various ways.
Accents give the SH-101 new possibilities in terms of expression and
variation.
See chapters ’Improved sequencer’ and ’MIDI’ for information on how

3 Improved sequencer
3.1 New features
While the original SH-101 sequencer features one sequence with a maxi-
mum of 100 steps, the SH-1oh1 provides 32 sequences with 120 steps each.
Additionally the sequences can be chained to create a song. This can be
done live while an other song is playing. Each step of a sequence can be ei-
ther a rest or a note. Additional attributes can be assigned to notes: glide,
volume accent and filter accent. These attributes can also be combined.
Despite the vastly improved functionality, a user who has experience with
the original SH-101 can still use the sequencer as they did originally.
3.2 Recording a sequence
To record a sequence press the LOAD button. This will select the last
sequence used for editing. To select a different sequence for editing, instead
of pressing LOAD, press and hold LOAD and use the keyboard to select
a sequence. Each of the 32 keyboard keys has a sequence assigned to it.
Release the LOAD button to start recording.
