Harmonic Oscillator

Post Modular

£645

For the first time in Eurorack, this oscillator module provides outputs for the first 8 harmonics as sine waves. Also included are triangle, saw, square waves. A voltage controlled mixer with various methods of address allows the user to scan, tilt and mix the harmonics from both panel and external voltage control. It is built on a discrete, all analog triangle core with an old school discrete transistor exponential converter. It has inputs for linear and exponential FM, the exponential with a reversing attenuator. Of course there s a 1 volt/octave trimmed CV input as well. Spec: 32HP 120mA +1

Where this comes from

The part other shops don't tell you. Three separate questions, kept separate on purpose, each with its source.

UK company
Registered at Companies House as POST MODULAR LIMITED, number 06889917. Checked 2026-08-29.
Means the business is a British legal entity, not a British-sounding name owned elsewhere. It says nothing about where anything is made.
UK operations
Not yet checked.
Means people employed here, or premises they actually work from. We keep this separate from the company badge because a registered office can be an accountant's spare room, and a company can be registered in Britain while everything it does happens somewhere else. Where we have not looked, we say so rather than assuming.
British-owned
Not established. Many companies file a statement rather than naming a controlling shareholder.
Read from the register of people with significant control, following the chain of holding companies. It does not gate anything: a firm can be made here and owned elsewhere, and that is worth telling you rather than hiding.
Where it is made
The maker doesn't say, so neither do we.
This is about the individual product, not the company. A British firm can sell things made abroad, which is normal and not a criticism. We would rather tell you which is which than average them into a score.
