Features

Most synthesizers today are so 'advanced' that they lack the simple ability to produce pitches outside of the standard 12 tones per octave, and do not allow something as basic as controlling the precise frequency of a sine wave. Lo-Fi Microsynth (HPLF) is a stand-alone [not a plugin] softsynth which fills the gap by placing emphasis first on tuning flexibility, using only the most basic building blocks of electronic sound. HPLF is compatible with the new U-PLEX keyboards and with TPX and standard MIDI controllers, and can communicate with sequencing and notation software such as Sibelius, Finale, Logic, Cubase, etc.

• loads .csv Tuning Table files (export files from free CSE and TPXE tuning editors)
• creates 1 virtual MIDI input port on Mac (Windows users can use MIDIYoke for this)
• scaleable polyphony, up to 28 voices
• basic waveforms:
  • sine
  • triangle
  • sawtooth
  • square
  • pulse
  • noise
• custom waveforms:
  • add arbitrary overtones to a fundamental (harmonic or inharmonic)
  • specify the amplitude and phase shift of each overtone
• envelope control:
  • Attack time and amplitude level
  • Decay time
  • Sustain amplitude level
  • Release time
• adjustable rate LFO, apply to:
  • pulse width
  • overtone amplitudes
• polyphonic pitch gliding (portamento)
  • glide time control
• panning, volume, and velocity control
• save patches and custom waveforms in human readable / editable XML text format
• automatic bug reporting
