Studiologic Sledge is a digital synthesizer which Italian famous keybed manufacturer Fatar released with the brand "Studiologic" in 2012. "ENGINE by waldorf" is printed. The synth engine is the same as Waldolf Blofeld and Blofeld Keyboard. However, Sledge has less parameters, less functions. However, Sledge has some advantages compared with Blofeld Keyboard. 61 keys, expression pedal connector, big knobs and switches, numeric keypad. At Sledge, the destination of modulatio wheel and aftertouch is the same. I agree. With SL(Sampling License) option, we can put sample waves in about 60MB flash memory. With version 2, split/layer is possible. If you do not like yellow, you can afford "Blask Edition". I do not say Sledge is a all-round type synth, but, a huge, light-weight, enjoyable synth.
With OS 2.1, I played and recorded first 40 presets.
| Sound | Comment |
|---|---|
| 001 SLEDGE POWER | Wavetable with modulation are used. OK, this is waldorf. |
| 002 ILLUSION | Polyphonic portament is a special feature of Sledge. |
| 003 TRUMPET MOON | When I attended to wind ensemble at junior high school, the first song I learned is the national anthem, 2nd is alma matter, 3rd is "Washington Post". I love the march. |
| 004 OMNI LORD | When I selected mono mode, portament is fingered. Vibrato wave is square. |
| 005 EMO CHORD | Sledge has 3 oscillators. In this program, 3 oscs make chord memory like sound. |
| 006 WHO FLASH | The category is bass. I am not sure how to play this sound. |
| 007 EIGHT BRASS | Maybe Jupiter-8 brass. I added too much vibrato. |
| 008 EIGHT LEAF | Digital brassy lead. I played the introduction of "Off The Stage", composed by Tsutomu Sakae. |
| 009 SINTHETICARP | An arpegio example. Filter envelope is working well. |
| 010 VINTAGE SINE | Osc1 is 32 feet, osc2 is 2 feet. Departed, but not organ like. Good job. |
| 011 MICRO SINE | Sine energy. |
| 012 SQUARE ARP | Shaking arpegio. Maybe chorus. |
| 013 WELCOME !!! | Filter modulated with sample and hold. Waldorf filter. |
| 014 SWEET PAD | Nice pad. Not much high frequencies. |
| 015 PEARL PAD | One more nice pad. Osc1 and 2 is saw, 3 is PWM. Good taste. |
| 016 SWEEP PAD | Osc3 modulated by LFO1 ramp. It makes sweep. |
| 017 SCREAM WAVE | An insect monster. Awful. |
| 018 FUSION CLAVI | Wavetable is used. I do not know which wave is used. Difficult. Wavetable knob should be a clicked encoder. |
| 019 GHOST | OK, it's a ghost. LFO1, 2 and wheel modulate osc1. LFO1 and 2 are sine, different speed. Wheel is ramp. Great job. |
| 020 JUPITER WIND | This sound has very long release. Because Sledge does not stop the sound when I switched to other sound, I could not stop this sound. Panic. |
| 021 INFABULUS | Osc1 is wavetable. Osc 2 and 3 are also working. Unique reverb character, polyphonic portament. Sledge(Blofeld)'s digital sound. |
| 022 MINI CLICK | Sledge has some kind of click noise, I guess. |
| 023 QUADRA TRIO | Is it ARP QUADRA? Heavy and comfortable sine modulation. |
| 024 SPACE JUPI 4 | Maybe Roland JUPTER-4. Cutoff is modulated by square wave. Tasty. |
| 025 SL TIGER | Organ sound made by wavetable. Sledge has wavetable, PCM samples, and be possible to add 2 oscs more. Those facilities are good for organ sound. However, no distortion, no rotary. We should use drive knob and chorus. |
| 026 SL CLAVI | Clave wave is included. Rotating WAVE knob is fun. |
| 027 HELICOPTER | Keys change sound slightly. Nice. |
| 028 OBERH PAD | Is it Oberheim? Maybe Matrix 1000. I sold the synth. |
| 029 ANYA BRASS | 3 saws brass. It sounds like PCM synth. |
| 030 VIBES | Vibraphone using wavetable. Not real, but I like it. |
| 031 SIRE LEAD | Pulse lead. Unique pulse or filter. |
| 032 ANALOG PAD | Is it analog? Waldorf Wave and Microwave with analog filters are imagined? |
| 033 ANALOGSTRING | Prophet like strings. Aftertouch controls filter cutoff. |
| 034 MICRO SAX | Pulse sax. Nice taste. Vibrato wave is square. It's easy to change to other wave. |
| 035 KE9 LEAD | I guess this sound is from "Karn Evil 9 Suite" by Emerson, Lake and Palmer. At YouTube, a cover band play this song very well(ELP KE9 1st Impression Part1 cover by a virtual ELP Cover Band). |
| 036 AQUA LEAD | 3 oscs lead. Cool. |
| 037 MULTI BASS | Modulated bass. One proposal. |
| 038 SQUARE PAD | Too much modulation, too. But, I should learn how to modulate my Sledge with this sound. |
| 039 1 OSC ARP | Simple sound has much pressure. |
| 040 ORGAN BRAKE | No rotated organ. With rotating WAVE knob, lots of organ waves come. |
I bought SL option. I loaded some waves downloaded from Studiologic and Waldorf web sites and recorded mp3s below.
| Sound | Comment |
|---|---|
| CONCERTGRND1 | Original program has no highs, I changed filter to 12dB/Oct and open it. 1990's PCM piano sound. Usable. |
| Power GRAND1 | "Power Grand" reminds me of MOTIF 1st generation. This sound is not as good as MOTIF. But I do not delete. |
| STUDIO GRND1 | Sweeping piano. I should have played higher range. |
In December 2017, I updated my Sledge os to 2.5.1. With 2.5.1, SL option is open for all users. I should have not paid. Factory wave data for SL option and Factory Presets are renewed. I played first 10 presets below. In my opinion, too much techno taste. With 2.5.1, output level is higher. Some things are gone.

|---|---|
| 001 SLEDGE | Wavetable modulation sound. Sledge has a "WALDORF" engine, I know. |
| 002 NICE WAVES | Cold German techno sound. |
| 003 WAVEQUENCE | Truly techno synth, now. |
| 004 CHILLAR | Cold. |
| 005 RESOPACKED | After recording, I normalize to zero dB. Something is wrong. I put a 1.5dB space at the top. |
| 006 BP SWEEP | Vivid Waldorf filter. Beautiful? |
| 007 COLD DREAM | One more cold sound. |
| 008 FORMATA | Difficult to play with beat. |
| 009 BIG DANCE | Bottom has gone at recording. Why? |
| 010 HOLD&CRY | I moved modulation wheel up and down. |
