ARPTON™ Synthesizer - Arpeggiator - Player is an electronic musical instrument emulated in software. It turns a PC keyboard into a MIDI input device and provides you with a way to play live music without use of a conventional music keyboard.
You no longer need to purchase expensive synthesizers. You can use your computer keyboard as your musical instrument.
You can play alone, play with any MIDI or MIDI-Karaoke accompanement, and sing into a microphone at the same time.
This may be useful when you first get started, or if you are on the move with ARPTON™ installed on a laptop and would like to play music without dragging a keyboard around.
ARPTON™ can generate sounds using any synthesizer (hardware and/or software) residing inside your computer, and uses your sound card to output the sound it produces.
You can decide whether send the output from the soundcard to headphones or to a pair of speakers.
Even the beginner will become very comfortable with the program from the first step.

For Starters: Allows kids and adults to play live music on a computer without buying a separate electronic musical instrument. Provides an opportunity to the unsure to perform using just a PC keyboard before spending money on the "real thing".

1. When using Java Sound Soundbank, arpeggio timing may be inaccurate during a live performance. (Playback of recorded arpeggios and other MIDI files is always fine.)
Solution: If you experience noticeable delay or unstable timing during live performance, try to select another available synthesizer.

2. When playing chords on the PC keyboard some notes are missing.
Solution: The reason for this effect is the difference in internal circuits of PC keyboards. Some PC keyboards does not allow to press too many keys at the same time. Some keyboards recognize more keys pressed at the same time, and some less. You may need some experience with using your keyboard to learn if it has such restrictions. You may need to try different keyboards.

Only 30 days email support is available for a Trial version.
The users who have purchased a license for a full unlimited version receive unlimited free technical support via email.
