Roland SH-4d: Hybrid Synthesizer for Live and Studio
· re:union Radio editorial · 3 min read
The Roland SH-4d packs 13 sound models, 60-voice polyphony, and a sequencer into a battery-powered desktop synth.
The Roland SH-4d is a portable desktop synthesizer that brings together analog sound models and digital sound generation in a single, battery-powered device. Roland promotes it as a "desktop powerhouse with hands-on workflow and deep synthesis tools" – a device that doesn't tie sound design to the studio but takes it directly to the stage.
At a glance
- 13 OSC models, including SH-101, JUNO-106, and Wavetable
- Up to 60 voices of polyphony, 4 Tone Parts plus 1 Rhythm Part
- Internal sequencer with 128 patterns and 64 steps per pattern
- Battery-powered via 4× AA batteries, up to 5 hours according to the manufacturer
A Synth Toolkit with 13 Faces
At the core of the SH-4d is its selection of 13 OSC models. In addition to standalone Roland classics like the SH-101 and JUNO-106, you'll find Cross-FM, Ring Modulation, Wavetable, Chord, and PCM synthesis, plus its own model for the Rhythm Part. This means a single device covers a spectrum that previously required several separate synthesizers.
According to Roland, polyphony extends up to 60 voices, depending on how much computational load the chosen sound models demand. The SH-4d is built from four Tone Parts and its own Rhythm Part, which can be independently assigned sound models and effects. For productions with multiple parallel sound layers, this approach allows for direct layering on the device, without external cabling.
Sequencer and Effects for Live Use
The internal sequencer stores 128 patterns with up to 64 steps each and includes features like Sub Steps, Flam, and Probability, which are usually found in dedicated groove boxes. For effects, there are five multi-effect systems with a total of 93 types available, complemented by nine Reverb, five Chorus, and five Delay types, as well as a Master EQ with compressor.
The SH-4d connects via USB-C for audio and MIDI, classic 5-pin MIDI, a 3.5mm clock input, and separate audio and headphone outputs. Roland explicitly describes the "rugged, grab-and-go design" as intended for mobile music production – a point that also makes the SH-4d interesting as a sound module or controller in larger hardware setups.

FAQ
Can the Roland SH-4d run purely on batteries?
Yes. In addition to USB-C bus power, the SH-4d operates with 4 AA batteries, providing up to 5 hours with Ni-MH batteries and up to 4 hours with alkaline batteries, according to Roland.
Is the SH-4d also suitable as a pure sound module?
Via MIDI IN/OUT, USB-C, and clock input, the SH-4d can be integrated into larger hardware setups and used there as an additional sound module or for supplementary percussion parts, for example, alongside a Roland TR-6S.
For live sets that need to cover both sound generation and playback, it's worth taking a look at current DJ controllers compared to CDJs.
