Owner Insights

We analyzed real musician discussions from forums and Reddit to find what players love, question, and tweak about MKS-50.

Features and functionality

  • The MKS-50 uses DCOs, contributing to its analog sound, despite some assuming it to be purely digital.

    Source
  • The L78MR05 regulator manages RAM enabling and backlight power, requiring attention when replacing the power supply to maintain these functions.

    Source
  • The MIDI THRU port on the MKS-50 is for outputting a copy of the input, not for connecting controllers or programmers directly.

    Source

Value and pricing

  • One owner acquired an MKS-50 for $260, noting it as an excellent value for a vintage analog poly synth.

    Source

Comparisons

  • The MKS-50 is likened to the Alpha Juno 1, with both offering unique sounds at relatively affordable prices.

    Source

Use cases and applications

  • It's noted that the chord memory feature is useful for sequencing polyphonic sounds despite limitations in monophonic sequencers like the BeatStep Pro.

    Source

Setup and maintenance

  • Replacing the MKS-50 power supply for UK use requires careful management of the 5V line, originally regulated by the L78MR05, which also sends a reset pulse to the CPU.

    Source
  • Using a 230-110V converter is an option, but it can be cumbersome due to its large size and noise.

    Source
  • Ensure 'MIDI EXCL' option is set to 'ON' for SysEx data reception on the MKS-50.

    Source

Mods and upgrades

  • The MCP100-475DI/TO chip is identified as a potential substitute for the L78MR05 in managing the reset pulse, bypassing the regulation function.

    Source

Software and compatibility

  • The PG-300 CTRLR panel may have hardcoded MIDI channels, affecting functionality; consider using a web-based editor for better results.

    Source
  • Send SysEx data slower if experiencing issues, as some interfaces may send it too quickly for the MKS-50 to process.

    Source
  • For Mac users, SysEx Librarian can be used similarly to MIDI-OX for transferring SysEx files to the MKS-50.
