Is the TD-3 a good first analog synth?

Yes, if you want a bass line machine rather than a keyboard synth. It is simple in architecture but the sequencer takes practice, so expect a learning curve before patterns come easily.

How does it compare with the Roland TB-303?

It copies the 303's oscillator, filter and step workflow and adds MIDI, USB and distortion. The original is vintage and costly; the TD-3 is the practical way to get the same acid sound.

Can I play it from a MIDI keyboard?

Yes. It has USB-MIDI and 5-pin DIN MIDI input, so you can trigger notes from a controller or DAW. It is monophonic, so only one note sounds at a time.

Does it have patch memory?

It stores up to 250 patterns across 7 tracks, but there is no separate patch memory for sound settings. You recall sequences, not saved sounds.

What is Poly Chain for?

Poly Chain links up to 16 TD-3 units so they play as one polyphonic instrument. One unit alone stays monophonic.

What comes in the box?

The synth and a 9V DC power adapter. No MIDI cables or patch cables are included.

What reviewers say

Owners and reviewers treat the TD-3 as a faithful, low-cost route to the TB-303 sound, with the added distortion and MIDI making it more usable than the original. Most criticism lands on the awkward step sequencer and the light plastic build rather than the sound.

What people mention

SoundPraisedOwners say the filter and oscillator get close to the classic 303 acid tone.
DistortionPraisedThe built-in overdrive is seen as a welcome extra that saves buying a pedal.
SequencerCriticisedReviewers find step programming fiddly and slow to learn.
BuildCriticisedThe plastic enclosure and small controls feel less solid than metal-built rivals.
ConnectivityPraisedUSB-MIDI, DIN MIDI and CV/Gate are praised for fitting many setups.
