G2500 Virtual Analog

G2500 is a virtual version of the classic ARP 2500 first created and released in 1970 by Alan R. Pearlman.

The G2500 is made from in-house developed proprietary and optimized virtual analog modules, to reproduce the unique and fat analog sound of the original, bringing it to your desktop. All the original control features from the ARP 2500 are there, and because you can save your carefully programmed patches, the G2500 is even better than the real thing.

Features:

• Twelve different virtual modules also found in the original:
  • 1002 Power Control.
  • 1004-P Oscillator.
  • 1004-T Oscillator.
  • 1005 Modulator Amplifier.
  • 1006 Filter Amplifier.
  • 1016 Dual Noise / Random.
  • 1027 Ten-Position Sequencer.
  • 1033 Dual Exponential Envelope Generator.
  • 1036 Sample & Hold / Random Voltage.
  • 1046 Quad Exponential Envelope Generator.
  • 1047 Multimode Filter / Resonator.
  • 1050 Sequential Mixer.
• A new 1102 I/O Control virtual module not found in the original.
• A virtual version of the 3001 Keyboard also found in the original.
• Play notes using 16 keys on the computer keyboard and selecting octave with two additional keys.
• Audio input from any system sound input device selected in the Preferences.
• Audio output to any system sound output device selected in the Preferences.
• MIDI input from any MIDI input device connected to the computer and selected in the Preferences.
• Recognizes MIDI All Notes Off, Note Off, Note On, and Control Changes.
• Save pieces of audio directly to disk in WAV format by the push of a button.
• Setup is fully user configurable, in order to choose which and how many of each module to use.
• Choose between two skins, Vintage and Black.
• Option to display tooltips for many controls.
• Use patch cables for even more connections than possible using the upper and lower matrix.
• Load requester to load new patches from disk.
• Save requester to save your own patches.
• Patches are stored as text-files in directories on disk, to be easily manageable with operating system tools.
• Zoomable user interface to easily go between a full overview and a detailed view of modules and controls.
• Choose between windowed or fullscreen mode.
• Studio quality 24-bit/96kHz audio in and out (*).
• Audio is easily sent to e.g. a software DAW (Digital Audio Workstation) using software such as "Soundflower for Mac".
• The G2500 is easily controlled from e.g. a software DAW using the IAC Driver found in the MacOS "Audio MIDI Setup".
• Five banks to store patches in memory, which is a benefit when creating new patches.
• Choose between Even Temperament and Bach-Lehman Temperament.
• Toggle bandlimiting on and off to stay below the Nyquist frequency (half the sample rate of 96kHz).
• An optional post-filter for more smooth acoustic transients.

(*) Audio is actually 32-bit floating point, and as values goes from -1.0 to +1.0, it is comparable to 24-bit audio and is easily converted to 24-bit by the operating system, if that is needed in the further signal chain.
