UDO Programmable Analog Synthesizer XL is the Hearn Morley XL8?


Follow-up to this post.

Note the differences (buttons & knobs).

Running a quick search for Hearn Morley XL8 brought me to Hearn Morley's website with the following info plus the third image below (they also had the 2009 pic).

"Hearn Morley manufacture a range of precision analogue audio building blocks in the form of miniaturized plug-in modules for 3rd party system development. These modules include Voltage Controlled Oscillators (VCO), Voltage Controlled Filters (VCF), Voltage Controlled Envelope generators (ADSR) and Voltage Controlled Amplifiers (VCA).

All Hearn Morley products are 100% tested, ROHS compliant and packed in anti-static protective packaging. We ship worldwide.

Just recently we've noticed some important analogue synth components go obsolete. These are +3300ppm/k temperature coefficient resistors (to compensate exponential converters and gm stages) and the LM3046M transistor array for which there is no real substitute. We made large purchases to keep them available to the synth DIY community."
