Peti uses hybrid FM synthesis technology and was developed primarily to emulate the sounds of the Harmonium, a member of the Reed Organ family, which is also known as the “pump organ”. The Harmonium, in its smaller form, is widely used in north Indian music, and its full, sweet sound is often used in pop and rock music, but Peti is not limited to this instrument alone. Peti is also capable of emulating a wide variety of reed organ variants, and can model timbres which resemble the many instruments in this family, ranging from from accordions to pipe organs, and even the famous melodica often used in reggae dub music. Peti was designed to allow the user complete control over a simulated Bellows mechanism, with 11 different modes providing ‘automatic’ or ‘manual’ pumping, with appropriate modulation of the sound-generation engine’s parameters. It also features two separate ‘reed bank’ simulators, allowing it to create the widest possible range of reed organ timbres via its sophisticated hybrid-synthesis system. Peti’s sound engine is also capable of emulating other key features of the Harmonium, including the body resonance of the instrument itself, the noise of air in the bellows and chambers, a ‘musette’ tremolo feature, and ‘key coupling’, which traditionally allows a single note to trigger two voices.
Features: Reed Banks 1 & 2 Controls
There are two Reed Banks modelled in Peti, with the same parameters available independently for each Bank.
These Reed Banks are responsible for the basic timbre of the instrument. However the two Reed Banks are not identical, which means that swapping settings between Bank 1 and Bank 2 may change the overall sound.
– Brighter : Adds more high frequencies in the timbre.
– Harmonics: Two different harmonic ‘flavours’ for each Reed Bank.
– Modulation: This parameter controls the overall amount of harmonics added.
Global Controls Resonance: This parameter sets how much physical resonance is modelled to simulate the wooden body of the Harmonium. Chorus: This parameter controls the effect which is often called ‘musette’ or ‘tremolo’ in accordian terminology. Ratio: This parameter changes the pitch difference between the two Reed Banks. Breath: This parameter controls the amount of ‘air noise’. Keys: This parameter controls the amount of keyboard noise simulated. Volume: This parameter controls the output level of Peti. Pitch: This parameter controls the master fine-tuning setting. Velocity Sensivity: This parameter allows you to adjust the instrument’s response to MIDI velocity. MaxVoices: This parameter sets the polyphony of Peti, from 1 (mono legato) to 16. Keyboard Coupler: This control emulates a mechanical ‘coupler’ which is found in some Harmoniums. It causes two notes to be played simultaneously by one key, with an interval which may be set to an octave, a fourth, or a fifth. Scale Changer: This control shifts the keyboard pitch up to 5 semitones up or down. This allows the player to change key but retain the same fingering, e.g. to play Eb major scale all on white keys.
** NOTE: This is NOT a demo, this plugin is fully functional. You can save and load presets!
** An 11 presets bank is included as FXB files along with “cloned” individual factory presets, and soundbank.
** Special note: The original “cloned” individual factory presets, and 41 Preset factory bank are included for your enjoyment.
** “Mono” is not implemented yet in this version.
The only difference with the current 1.0 Release version has an animated keyboard GUI, and minor graphics changes such as removal of the words “FREE BETA” from the Interface.
