Product Information
Full details
The SOMA Pulsar-23 is an organismic drum machine for electronic musicians and sound designers seeking unique, evolving sonic textures and rhythmic patterns. Its key benefit is the ability to generate a vast range of sounds from percussion to melodic lines and soundscapes through its semi-modular design and unique interaction methods. A potential caveat is its complexity, which requires dedicated learning to master its full creative potential.

Extended Product Information
FAQs
What is an "organismic" drum machine?
It refers to a design philosophy that draws inspiration from biological processes, aiming for sounds and patterns that feel alive, evolving, and non-linear, rather than strictly mechanical or digital.
Can the Pulsar-23 be used with other modular synthesizers?
Yes, it is designed to integrate with other modular systems using standard CV and MIDI connections. It can act as both a sound source and a controller within a larger setup.
How complex is the learning curve?
The Pulsar-23 has a significant learning curve due to its unique approach to synthesis and its semi-modular design. It requires dedicated time to understand the interaction between its 23 modules and its various control methods.
What is circuit bending on this device?
Live circuit bending allows users to temporarily alter the device's internal circuitry during operation by touching specific points, leading to unpredictable and often chaotic sonic results.
Can I create melodic lines with the Pulsar-23?
Yes, while primarily known as a drum machine, its versatile synthesis capabilities allow for the creation of basslines, drones, and melodic sequences, especially when using its CV control features.
Is it possible to save presets?
The Pulsar-23 is an analog semi-modular device, and as such, it does not have digital preset saving capabilities. Sound creation is based on physical patching and knob settings.
What is the power requirement?
The device requires a specific power adapter, which is usually included. Please refer to the product's manual for exact voltage and amperage specifications.
Troubleshooting
No sound output
Ensure the unit is powered on, volume is turned up, and audio output is correctly patched to your mixer or interface. Check if any modules are muted or have their output attenuated to zero.
MIDI synchronization issues
Verify MIDI cable connections and ensure the Pulsar-23 is set to receive MIDI clock. Check that the sending device is also configured correctly for MIDI clock output.
Unexpected or undesirable sounds
This is often a feature of the Pulsar-23. Experiment with different patching and module settings. Refer to the manual for detailed explanations of each module's function and interaction.
CV inputs not responding
Confirm that the CV source is providing a valid voltage signal and that the patch cable is securely connected. Ensure the correct CV input on the module is being used.
Body conductivity not working
Ensure your hands are clean and slightly moist. Experiment with touching different conductivity points. The effect can be subtle and dependent on individual skin resistance.
Pros and Cons
Pros
- Offers unparalleled sonic flexibility and unique sound generation capabilities.
- Its semi-modular nature encourages experimentation and deep sound design.
- Can function as a standalone instrument or integrate seamlessly with other gear.
- The inclusion of body conductivity and circuit bending opens up novel performance avenues.
- High-quality analog sound and robust build.
Cons
- Steep learning curve due to its complex and unique interface.
- May be overwhelming for users accustomed to conventional synthesizers or drum machines.
- Limited number of physical patch points compared to traditional modular systems.
- Requires careful attention to gain staging and signal routing for optimal results.
- Not ideal for users seeking immediate, pre-set drum sounds.
Setup, Compatibility & Care
Setup:
Connecting the Pulsar-23 involves understanding its input and output jacks for audio, MIDI, and CV signals. For stand-alone operation, power is supplied via the included adapter. MIDI synchronization can be achieved by connecting a MIDI source to the MIDI IN port. CV control requires patching control voltage sources (like LFOs or sequencers) to the designated CV inputs on the modules.
Compatibility:
- MIDI: Compatible with standard MIDI keyboards, sequencers, and DAWs for note and clock data.
- CV/Gate: Supports standard Eurorack and other modular synth voltage levels for control signals. Ensure your external modules are compatible with the voltage ranges used by the Pulsar-23.
- Audio: Outputs standard line-level audio. Can be connected to mixers, audio interfaces, or effect pedals.
Care:
- Keep the unit in a well-ventilated area to prevent overheating.
- Avoid exposing the device to moisture or extreme temperatures.
- Clean the exterior with a dry or slightly damp, soft cloth. Do not use abrasive cleaners.
- Handle patch cables carefully to avoid damaging the jacks.
