Surf the synthetic wave, sample your music.
Sledge 2.0 introduces new features and sound innovations that set the instrument above any competitor, thanks to a mix of pure synthesis and sound sampling.
In addition to the incredible sound engine and the user-friendly vintage style control panel, the new features further expand the synthesizer's power and versatility.
Auto Dual Mode, mix the sound
Combine and play two sounds at the same time, in Split or Layer mode.
Every sound combination can be stored in any of the 999 available presets.
Hold the loop and pitch the sound
Pitch and Hold functions can be enabled separately for the Lower and Upper sounds in Dual Mode, allowing you to keep the sample loop running while playing the upper sound.
Elevate your performance.
Let your samples play
Sound samples and new waves can be loaded in the internal memory, played by OSC 1 and modifiable by all parameters of the control panel, adding other oscillators, setting filters, envelopes and effects.

Firmware and updates
By installing the 2.5.1 version or upper, you will not be able to downgrade to versions older than 2.5
- Connect Sledge to the computer with a standard USB cable and power it ON;
- Verify that it is recognized by the computer (according to the local settings);
- Download the new OS and play it with a MIDI Player application (like MIDI OX for Windows or QMidi for Mac);
- Note: before sending the OS/MIDI file, verify that the MIDI OUT data of the PC are sent to Sledge;
- A message on the display will notify that the update is operating; wait for the end of the playing/programming procedure on the computer player;
- Turn Sledge OFF/ON: the new Firmware version will be shown on the display.
Bug fix: disabled protection of the Factory Samples (of Firmware 2.5) that could not allow to install new samples.
Enhanced audio output level (+ 100% peak level) for a stronger, cleaner and fatter sound.
Synchronized LFO2, allowing to keep the same modulation phase on all notes.
Sample Licence included (free of charge) that allows all previous Sledge to play samples, with no need of further updates or extra costs.
Implementation of the MIDI standard message "All notes Off" (also known as "MIDI panic") in case of hanging notes after releasing all keys (also coming by MIDI IN) not correctly stopped by the related "note off". To activate the command, set MASTER VOLUME to zero (all the way to the left) and then rotate it again, to reach the desired value.
Protection against rare random hanging notes (created by the Arpeggio function) that could occur when selecting many programs with Arpeggio in a very fast sequence.
Protection against a very rare random INIT sound, recalled when rotating or selecting many Programs in sequence, under stressed conditions (full memory, many samples installed, complex programs).
Fast and correct auto-setting of the Arpeggio TEMPO (as stored in the related Program) when recalling various Programs withe Arpeggio active, in a fast sequence.
AUTO DUAL MODE: Sldge 2.0 can now play two sounds at the same time, in Split or Layes mode; the feature is controlled by a new page of the Global function and allows to simply keep one note (for Split) or more notes (for Layer) and then slect a new sound, that will be added to the previous sound; as any other sound, also Dual Sound combinations can be permanently stored in any of the 1.000 avaiable presets.
GLOBAL PITCH & HOLD CONTROLS: a new Global page allow to enable the Pitch and the Hold separately for the Lower and Upper sounds in Dual Mode, allowing to use the Pitch bend on the Upper sound (i.e. for solo parts) and the Hold pedal to control only the Lower (to kepp playing a Drums groove or as a Damper for a Piano sound) and vice-versa, or to enable Pitch Bemd and Hold or both Upper and Lower sounds.
REVERB + DELAY: a new function allows to mix both effects; the Reverb keeps the setting previously selected, while the real time controls (time and level) allows to set the parameters of Delay also when mixed to the reverb.
SAMPLES: sound Samples can be trasmitted to Sledge and loaded in the internal 60 Mb of Flash memory, played by OSC 1 and modifiable by all parameters of the control panel, adding oscillators 2/3, setting filters, envelopes and effects. This feature can constantly expands the instrument's sounds and create a totally new combination of synthesis and sampling.
ENHANCED POLYPHONY: the total maximun number or notes that can be playes at the same time have been expanded to 24, allowing to get a better real time control over the new sound pollibilities from synthesis and sampling together.
When Sldge is connected with USB cable to a computer or MIDI Controller, with the control "All controls reset" the volume goes now to value 127 (instead of 0 or minimum, as in previous versions).
Protection of the system when receiving data from MIDI IN during Power on; in previous version the instrument could ramdomly stop working correctly.
Notes on the highest octabe could remain sustained when the instrument was transported to other tonality (different from 0=default).
Arpeggiator speed adjustments and correct initial value.
Improved stability on potentiometer's position and related value.
