Product Information

Full details

The Soma Laboratory Pulsar-23 is an organismic drum machine designed for electronic musicians and sound designers seeking unique, evolving percussive and melodic textures. Its key benefit lies in its highly experimental and hands-on semi-modular design, offering deep sound manipulation and live circuit bending capabilities. A potential caveat is its steep learning curve due to its unconventional interface and synthesis methods, making it best suited for those who enjoy deep exploration.

Extended Product Information

FAQs

What kind of sounds can I expect from the Pulsar-23?

The Pulsar-23 excels at creating unique, experimental, and often unpredictable electronic sounds. It's not designed to replicate acoustic instruments but rather to generate percussive textures, evolving rhythms, basslines, and soundscapes.

Is the Pulsar-23 a modular synthesizer?

It is a semi-modular instrument. It has a fixed number of modules (23) but allows for extensive interconnection via patch cables, offering a deep level of sound design exploration similar to modular systems.

Can I use my body to control the Pulsar-23?

Yes, the Pulsar-23 allows for live circuit bending and incorporates conductivity sensors, enabling you to use your body's electrical resistance to manipulate sounds in real-time.

Does it work with other modular synthesizers?

Absolutely. It features CV (Control Voltage) inputs and outputs, making it highly compatible with other modular synths and CV-controlled gear.

What is the primary use case for the Pulsar-23?

It's ideal for electronic musicians, sound designers, and experimental artists looking for a hands-on instrument to create unique rhythmic patterns, sound effects, and atmospheric textures.

Do I need to know synthesis to use it effectively?

While some understanding of synthesis principles can be helpful, the Pulsar-23 is designed for hands-on experimentation. You can achieve interesting results through exploration, though a deeper understanding will unlock its full potential.

What are the "screws" on the Pulsar-23 for?

These are touch-sensitive points designed for live circuit bending and interaction. Touching or manipulating these screws directly affects and alters the sounds being produced in real-time.

Troubleshooting

No sound output

Ensure the unit is powered on, the volume is up, and the audio outputs are correctly connected to your mixer or speakers. Check if any modules are muted or have no signal path.

MIDI control not working

Verify the MIDI cable connection and ensure the Pulsar-23 is set to receive MIDI (check device settings if applicable). Confirm your MIDI controller or DAW is sending MIDI data to the correct channel/port.

CV signals are erratic or unexpected

Check that your CV patch cables are securely connected at both ends. Ensure the voltage ranges are compatible and that you are not overloading any inputs. Consult the manual for specific CV behavior.

Unit powers on but no functions respond

Try resetting the unit by powering it off and on again. Ensure all module connections are secure. If the problem persists, contact support.

Sound is distorted or clipping

Reduce the output volume on the Pulsar-23 or the input gain on your mixer/interface. Check for any overloaded signal paths within the module patches.

Pros and Cons

Pros

  • Offers unparalleled sound design possibilities for unique percussive and electronic textures.
  • The semi-modular and circuit-bending features provide deep experimental potential.
  • Flexible control options (stand-alone, MIDI, CV) allow integration into various setups.
  • Built-in analog effects enhance its sonic capabilities.
  • High degree of tactile control promotes an intuitive and hands-on workflow.

Cons

  • Steep learning curve due to its complex and unconventional design.
  • Primarily suited for experimental sounds; not ideal for users seeking traditional acoustic drum sounds.
  • Can be intimidating for beginners in synthesis or modular environments.
  • Requires dedicated space and time for exploration and mastery.
  • May require additional modules or devices for full CV/MIDI integration depending on the user's setup.

Setup, Compatibility & Care

Setup:

The Pulsar-23 is designed for immediate use. Connect it to a power source. For MIDI control, connect a MIDI controller or DAW via the MIDI IN port. For CV control, use standard patch cables to connect to other CV-compatible instruments or modules via the designated CV IN/OUT jacks.

Compatibility:

  • MIDI: Supports standard MIDI notes and clock signals.
  • CV: Compatible with standard Eurorack or other modular synthesizer voltage levels (typically 0-5V or 0-10V).
  • Audio Output: Standard 1/4" audio outputs for connecting to mixers, audio interfaces, or amplifiers.

Care:

  • Keep the unit clean and dust-free. Use a dry or slightly damp soft cloth for cleaning; avoid abrasive cleaners.
  • Protect from extreme temperatures and humidity.
  • Handle patch cables and module connections gently to avoid wear.
  • Store in a secure location when not in use to prevent damage.
