The eagerly awaited observe-up to 2018's Chipsynth PortaFM sees a lot-cherished Canadian builders Plogue recreating the soundchip from the Sega Mega pressure/Genesis 16-bit video games console of the 90s, and deploying it as the groundwork for a plugin synth (VST/AU/AAX/standalone) fitted for each old chiptune-vogue noises and sophisticated modern sounds.
Chipsynth PortaFM modelled the OPLL (YM2413) chip found in Yamaha's PSS line of FM devices, and Chipsynth MD stays with the equal manufacturer and synthesis fashion, "bit- accurately" emulating the Mega power's OPN2 (YM2612) processor.
No samples are concerned – here's pure coded emulation, taking in the full architecture, correct right down to the OPN2's odd 9-bit DAC, which used time-division multiplexing to manage playback of 1 pattern at a time from every channel in sequence.
It even includes a VGM participant for playback of raw Mega force sound files, complete with mute and solo of channels within the mix, adjustment of tuning and playback velocity, and one-click on copying of sounds to the synth's two patches.
In actuality, Chipsynth MD includes six full and impartial Mega force emulations – one for each of its six stackable voices. every voice comprises now not simplest the OPN2's six 4-operator FM channels, however also three rectangular wave and one noise SPSG channels, and – replacing one of the crucial FM channels when required – a sample player, each of which we'll come returned to.
every of the six OPN2 channels will also be set to considered one of two FM patches – A or B, each functionally identical – with layer 6 also offering the aforementioned DAC-sampler player as an option. Eight preset algorithms are selectable, and the 4 operators circulation round to visually signify the signal movement from carrier(s) on the bottom row via modulator(s) above. just a little of color-coding would were welcome here, were we to nitpick. Very helpfully, even though, a gigantic library of "classic" OPN2 patches is onboard, presenting plenty of quality beginning elements in your personal algorithmic manipulations.

efficiency and verdictThe operators facilitate an outstanding level of control, together with degree, Detune and as much as 15x frequency multiplication for pitchshifting and waveshaping. A 5-stage envelope – the extra stage being a 2d Decay section in between the sustain and unlock – contours the dynamics, and eight particular looping envelope shapes are handy by way of a graphically consultant menu panel. These are basically supposed for FX patches, however they have got their melodic makes use of as smartly. Operator 4 features a remarks knob for self-modulation: the specific impact this has depends on the patch, nonetheless it often brightens and distorts the sound.
Alongside the general speed sensitivity environment, envelope pace and volume are modulatable with the aid of pitch. Vibrato (pitch) and Tremolo (volume) LFOs are additionally onboard, the previous applied globally and its cost inexplicably buried away in the Settings page, regardless of there being greater than adequate room for it basically UI, and the Tremolo working per-voice and activated independently for every operator.
also invaluable of notice is Channel 3's special Mode, by which the operators in its chosen patch can be personally detuned and the entire patch retriggered at audio cost for an edgy, aggressive 'synced' sound.
The SPSG was a feature of the Mega drive's video processor, enabling compatibility with the Sega master gadget, and it includes three rectangular wave channels and a noise channel, the last switchable between prolonged noise and a 1/16 cycle, and outputting at considered one of three fastened frequencies, or monitoring the frequency of Channel 3. The SPSG does have its uses for organs and percussion, however is terribly an awful lot secondary to the leading FM channels within the grander scheme of things.
The DAC pattern player, meanwhile, seems to be peculiarly for triggering individual hits from drum loops, because it instantly slices the imported pattern and maps the effects to consecutive keys with out a choice to with ease pitchshift/timestretch the total pattern across the keyboard. Bit discount and jitter are accessible for messing issues up, and it works smartly adequate, however we don't in fact see the element.
All ten channels (six FM/DAC and 4 SPSG) are brought together within the Stack web page, the place they're for my part turned on and off, tweaked when it comes to key range, detune, quantity, pan,
all of it comes collectively within the Stack page, where the ten channels are assigned, blended, detuned and delayed extend and glide time, and locked to fixed frequencies if required. Modulation is applied in the Mod Matrix and Steps pages (see Mega modulation), and the consequences web page residences a extremely well-fitted Arpeggiator and three powerful signal processors: chorus (inspired by the Roland Dimension-D), atmosphere Reverb (with pre-prolong and diffusion) and extend (four discrete taps with feedback and lengthen time modulation).
With its bizarre interface, Chipsynth MD definitely isn't the easiest of synths to software, however the preset operator patches and astounding consequences greatly pace up the manner of getting from sonic (we'll not hunch to hedgehog puns) concept to closing product.
What's most fantastic of all, although, is how punchy, clear, voluminous and animated it can be made to sound, thanks in no small part to that six-layer structure and the depraved step modulation sequencers. It's versatile, too, fortunately serving up every thing from basses and percussion to keys, pads, plucks and FX.
Make no mistake about it: Chipsynth MD is a first-class retro FM synth in the broadest sense, able to excess of the blips and bloops its gaming origins indicate.
MusicRadar verdict: enjoyable and least expensive, Chipsynth MD nails the Mega force emulation and brings it up thus far with a wealth of modern points.
