Simone Sedda

2 Musical Collectors items: Casio SA-39 and Bontempi Concertino 25

Both Great Sounding minikeys, in perfect working condition and complete.

The Concertino 25 has 3 very piercing Lead sounds combined with a nice variable speed Chorus. High and low octave settings, 3 very analog and electronic sounds, Brass Flute and Fantasy. In the original box and with the original manual. A real collectors item! 4 x AA Batteries are included. Also works with the supplied Power Adapter.
This rare mini synth is extremely compact: 40 x 6.5 x 3.5 cm

The other gem is a  Casio SA-39. This synth employs a wavetable synthesis engine that mixes 2 looped samples using independent, partly very complex algorithmic volume and pitch envelopes (made by program loop synthesis?). Most samples are of low resolution and typically short looped static waveforms, which gives these instruments a characteristic cheesy digital lo-fi appeal; the sounds tend to be cold, harsh and have much digital aliasing noise, which is very different from the always quite warm, bassy, smooth and noble sounding Yamaha FM timbres. The Casio SA series instead sound tinny, squeaky, thin and kazoo- like - it's exactly that sound you likely would have hated in the early 1990th, when it was the over- glorified, over- used and almost only available timbre in home keyboards and PC wavetable soundcards. (When it would be my only sound source, I also would hate it.)

But nowadays in the age of high quality sampling and modern software synthesizers the trashy sound style of the Casio SA wavetable squeakboxes sounds special again! And not least because they include certain characteristic algorithmic sound effects; many sound presets contain reverb or echo effects (simulated by envelope) and there are even melodic arpeggiator loops and disharmonic and atonal effect sounds like wicked sirens, sci-fi- and tekkno noises and also various drum kit modes with low- res percussion samples. Also the incredible static and naughty tooting "brass ens" and the squawky "elec organ" are very remarkable timbres of this hardware series. Many of the preset effect sounds are time- dynamically playable, i.e. the sound of the release phase (often reverb or echo) changes with the key press duration (Yamaha FM keyboards do this also), which makes the sounds behave less static than normal sample based sounds. 

Features:
- 32 keys
- 100 Sounds
- 19 Drums only Rhythms (Select + White Keys)
- 13 Accompaniment Styles with Drums, Bass and Chords (Select + Black keys)
- jacks for AC- adapter (included!) & mini-jack headphone / line output
- Size: 61 x 17 x 5.5 cm

The Drums of the SA-39 sound quite unique due to its digital blip percussion; they were already used e.g. in various early acid house musics. The drums are made from unique rough and blippy digital waveforms (possibly these are extremely low- res loop samples with decay envelope). The cymbals employ a rough and semi- metallic digital waveform.
The drums as well as the 100 preset sounds are truly AMAZING. 

The SA-39 is also in excellent condition, and complete with battery cover and a high quality power supply.
