Yamaha PSS 390 mini synth demo


The Yamaha PSS 390 is the “toy keyboard” claimed to have the better and best sounding FM synth engine in the toy range.
It has 100 tones that can be widely modified with the tone controls, instead of button +/- it features sliders to edit the synth parameters.
The only lack is the midi control that however can be added by retrofit.
It can be seen in action in the videos of the band “the Apparat Organ Quartet”.

Yamaha CS 01

Yamaha CS01

The CS-01 is a funky little synth!
It may seem a toy but is a real analog synth in a small case.
The structure is quite simple, justa simple LFO, a “VCO”, VCF and ADSR.
I wrote “VCO” because even if the yamaha labeled it VCO but it is in fact a DCO.
The sound of the oscillator is however real analog, and “phat sounding” in a typical japanese way, and it reminds the classic analog sounds of the early 80’s.
The oscillator offers a good selection of waves (TRI, SAW, SQUARE, PULSE, PWM) and feets(4′ 8′ 16′ 32′ and noise).
The most powerful is the sound of PWM, which is really fat and “wide” sounding.
PWM has its own speed control too (indipendent from lfo).
The LFO is only a tri wave useful for vibratos and wah effects, its not extremely fast, but works well for all the classic sounds.
VCO also have a “glissando” instead of portamento/glide, which means that it can jump from a note to another passing through the notes in the middle.
The VCF is a 12dB lowpass with resonance and EG depth.
The resonance is controlled by a switch that turns it on or off, but it’s possible to modify the control to have a real resonance control adding a knob.
On the MK2 model the filter use a different structure (it has a 24 dB slope instead of 12) and has the resonance controlled by a slider.
The filter is, as other old yamaha monosynth, very smooth and “bubbling”, even with resonance tutned on the filter never eat the low frequency range, offering a wide variety of colour even as a bass machine.
The CS01 is mainly a bass and lead machine, the bass is always rounded, and punchy, for the classic 80’s arpeggio or for techno bass sounds.
On the lead side it can sound quite minimal and smooth or rich using the pwm, it can also reproduce easily the classic retrocomputer sounds !
Despite the toys look with the built in speaker this a lightweight classic 80s monosynth that can do most of the analog mono-sound without any problem of space in the studio and being very reliable.

Yamaha VSS30 preset sounds editing

I’ve made this video to demostrate how the the yamaha  VSS30 can mangle  the internal waves.
Everything is done only with the VSS , no external efx and NO samples.

Yamaha VSS-30 (8bit sampler) review

Yamaha VSS 30 - 8bit sampler

Yamaha VSS 30 - 8bit sampler

Cheap is not always bad, and toy keyboards are not always and only toys.
This is the case of the Yamaha VSS30, a toy keyboard from the late 80’s, that’s today a widely used musical intrument for experimental musicians and not a child/school keyboard.

The reasons why the vss3o is so appreciated for particular musical genres are its sound and the manipulating capabilities.
The engine of the keyboard is an 8bit sampler with synthesis capabilities, that can sample and resample layering sounds.

All the edit is done with buttons on the front panel without any menu , and the variations are realtime effective.
There is :

  • ADSR Envelope fore the volume of the sound
  • Loop function
  • U-turn (plays the sample fwd and rew)
  • Reverse (to reverse the sample)
  • ECHO (is a”envelope effect”, like a long decay-release)
  • Fuzz
  • Frequency Modulation
  • Amplitude Modulation
  • Vibrato

There are 12 preset sounds that can be manipulated with efx (adsr, echo, fuzz, fm, am , vibrato):

  • Piano
  • Harpsicord
  • Banjo
  • Vibes
  • Marimba
  • sample
  • Crystal
  • Strings
  • Jazz organ
  • Brass
  • Clarinet
  • Galaxy

The preset sounds are samples of DX7 presets , I presume, from the sound that is quite synthetic and not natural.
But the more gorgeous power is in the capability of mangling the sample with the efx/synthesis.
Every effect is editable with the data entry buttons.

So as the adsr can shape the loop and u-turn can create some really particular loop textures if used as pads, and the FM and AM can go from low tremolo/articulated low pitchmodulation , to fast tremolo and vibratos/FM sounds.
The overwrite function layer the sample in memory with incoming audio material creating a new sample.

All in all this is a little but awesome LO-FI experimental machine, as it’s the only toy keyboard that can do all these things without modding (as the VSS200, a larger version of the VSS30).
The sound is warm, “pixelated”, lo-fi, and every sample sounds really different from the source.
It’s perfect for IDM, experimental music, but also for pop or mainstream as many professionals use it in their recordings like Sigur Ros, Portishead, Trent Reznor, Autechre, Bjork.
