Sounds like: A noise sweep with a rising tone underneath, pulling upward into a drop.
A hybrid of White Noise Sweep FX and Riser / Uplifter FX — filtered noise rising alongside a pitched oscillator sweep, giving more directional 'lift' than pure noise alone.
Open this patch in the interactive PatchpadCorrected: two tracks are still needed (Digitone II is one voice per track), but both now use the right machine. Track 1's noise was an FM approximation (ALGO 8, a very high RATIO A) — WAVETONE has a real noise generator (page 3: NLEV level, TYPE GRAIN/TUNED/S&H, CHAR grain density from white noise to very grainy, BASE/WDTH noise filter), so Track 1 mutes both oscillators (LEV1/LEV2 0) and runs the noise alone through the FLTR sweep (ATK opens it over the rise, high RESO for the peak; TYPE 64 is the LP/BP/HP morph's midpoint for a bandpass-like character). Track 2's pitch rise used a non-existent 'Pitch' LFO destination; it now runs a one-shot (MODE TRG) unipolar Ramp on WAVETONE's TUN1, a real cents-based destination. Values are starting points to adjust by ear.
Two tracks, layered together in the pattern -- Track 1 approximates noise with NLEV pushed high on SY RAW plus a wide DET spread; the filter's own high-resonance Lowpass sweeps it open over the rise (no true Bandpass exists on digital-voice tracks 1-8). Corrected: this LFO used to target an invented 'Pitch' destination — Syntakt's LFO destination list (manual Appendix C) has no direct pitch option, so it now targets the machine's own TUNE knob (parameter 1), the real route to pitch modulation. (For hard one-shot pitch falls Syntakt also has native sweeps: BD MODERN's SWEP sets pitch-sweep depth and time.)
The pitch layer genuinely needs the Mod Matrix (a slow-rising Mod Envelope 2 routed to Oscillator 2's pitch) -- Summit's exact Mod Matrix menu wording isn't fully detailed in this project's reference material yet, so the routing shown is the correct real mechanism but the precise on-screen labels should be confirmed against the hardware.
Osc 1 is Noise: Wave is the noise Type (particle through white to metallic), Timbre is the Rate and Shape is the Balance with a tonal wave. Osc 2 is BasicWaves with Morph at 50 (pure sawtooth): the Morph knob runs from a square (0) through a sawtooth (50) to a double sawtooth an octave up (100), Sym only changes the pulse width below 50, and Sub adds a sine an octave down (0 here). Mod Matrix: the CycEnv row to the Cutoff column at +70. Mod Matrix: the CycEnv row to the Pitch 1+2 column at +80. MiniFreak's two real oscillator engines mean the noise layer and the pitched layer genuinely coexist in a single voice -- Osc 1 supplies the noise, Osc 2 the pitched saw. One Cycling Envelope (a second, distinct modulation source from the main hardwired-to-VCA Envelope) drives both the filter cutoff and Osc 2's pitch together via the Modulation Matrix, so the noise's filter sweep and the saw's pitch rise move as one continuous gesture. Values are on MiniFreak's native 0-100 scale.
Typhon has only one VCO pair (blended and detuned via the single WAVE/TUNE 2 knobs), not two independent layers, so the noise-vs-pitch split from the other synths is approximated by leaning the WAVE blend and wide TUNE 2 detune toward a dense, unstable texture rather than a clean pitched tone. M1's real DEST list includes CV1 (pitch, in semitones) with LVL scaled directly in semitones for that destination (per the manual's own CV-scaling note) -- LVL 19 gives just over an octave and a half of rise, driven by M1's own Envelope mode (A/D/R/S) rather than an LFO, for a one-shot rising sweep rather than a repeating cycle.
Hydrasynth's MIXER has a real dedicated Noise generator, used here for the noise layer instead of a noise-flavored oscillator waveform. Filter 1's ENV 1 AMOUNT plus Envelope 1 (pre-wired to Filter 1) drives the noise layer's filter sweep with no Mod Matrix entry needed. OSC 2's pitch rise isn't pre-wired to anything, so a free-assign Envelope 3 (Hydrasynth has 5 identical envelopes total, 3 of them free-assign) is routed to OSC 2 Pitch via the Mod Matrix -- its Attack reaches full Sustain level and holds, giving a one-time rise rather than a repeating cycle.
A genuine two-layer FX combining White Noise Sweep FX and Riser / Uplifter FX's techniques — on single-voice synths (Dreadbox Typhon), consider prioritizing one layer or pairing with a second instrument. MiniFreak's two real oscillators handle both layers in one voice directly, see its own guide.
