Critic Reviews

Teisco SX400 [Retrozone]

soundonsound.com

The Teisco SX-400 is a curious relic from the analog synthesizer era, notable mainly for its missed potential. Despite boasting four independently-tunable VCOs and intriguing features like aftertouch and a stereo Ensemble effect, its gutless filters and sluggish envelopes make it a sonic underperformer. The SX-400's notable drawbacks, such as a lack of waveform mixing options and cumbersome design, overshadow its few redeeming qualities. While it can produce some unexpectedly pleasing sounds and offers more sound-shaping capabilities than some contemporaries, its impracticality and rarity make it a synth more suited to collectors than musicians seeking reliable performance.

Teisco SX-400 (EMM Jan 82)

muzines.co.uk

The Teisco SX-400 synthesizer shines with its versatile polyphonic capabilities and rich sound palette, making it an attractive choice for those entering the realm of polyphonic synthesis without breaking the bank. Its standout features include pressure sensitivity and a variety of playing modes, which add expressive potential to performances. The ensemble effect enhances its stereo presence, despite some minor background hiss. However, the lack of an arpeggiator is a noted omission, and the absence of a protective lid might require additional investment in a flight case. Overall, the SX-400's robust build and innovative programming features offer great value for its price, appealing to both synth enthusiasts and performers alike.

Teisco SX400 (12T Nov 82)

muzines.co.uk

The Teisco SX-400 synthesizer attempts to offer versatility with its multi-mode polyphony and numerous controls. However, its bulky design and lack of standout features make it a cumbersome choice. The sound quality disappoints with weak filters and flimsy oscillators, and the chorus ensemble unit is notably noisy. Programming is standard but outdated, lacking intuitive controls found in other contemporary synths. The SX-400’s second touch feature is less effective, and without an arpeggiator, it falls behind lower-priced competitors. Despite a sturdy build, its high price tag is unjustified, especially when compared to more capable alternatives like the Korg Polysix.
