As a reminder, the Korg DDD-1 was a digital programmable drum machine from the mid-80s with 18  electronic drum sounds including kicks, snares, toms… Like the DDD-1, the DDD-5 was also a digital drum machine from the mid-80s with only 14 electronic drum sounds. It was a newer but less professional version of the DDD-1. They also had a significantly different user interface. They had an option to load additional sounds using specific ROM cards.

The new WaveREX DDD-11 and DDD-15 cards are PCM cards that can be freely loaded with samples. They feature a display with up/down buttons and can store up to 32 banks. The hardware units, however, can only read a single bank with up to 8 sounds per card. So you select the bank on the card (1-32) and the drum machine then recognizes it as a card. There is no length limit for the sounds.


The transfer is straightforward. On the card, you can find a micro-B type port (rrr wrong port decision) that allows you to connect the card to your computer. From here, you can transfer the samples using the WaveREX editor. It is used to convert samples from WAV and AIFF format as well as for the card organization. Unfortunately, the editor will initially only be available for Windows. A macOS version is coming later.

There is more to discover in the editor. The imported samples have the same character as the original. So with aliasing effects when transposed. Cool, the editor gives you the option to switch between a legacy mode and an anti-aliasing mode. In anti-aliasing mode, it reduces the sample rate of the samples and it will remove the effects. However, with no transposition in the device.

A bit pricey but a beautiful product that breathes new life into vintage Korg drum machines

WaveREX DDD-11 and DDD-15 will be available soon for 157,94€ +VAT each.
