This is the Teenage Engineering pocket operator PO-133, a palm-sized synthesizer. The basic functions are the same as the PO-33 K.O! from the same Pocket Operator series, with the only difference being that it includes Street Fighter phrases by default (the phrases can be deleted, so it can be used exactly like the PO-33 K.O!). This is a Street Fighter II collaboration model, and includes sampled phrases such as "Hadoken!". This is a valuable model that is no longer sold. A genuine teenage engineering silicone case is also included. After purchase, I only checked the operation, and the case is almost unused, so I think it is in very good condition. The hanger has been removed to fit in the case. I have confirmed the operation as far as I can tell. Please check the condition and accessories in the images from the second image onwards. I am also listing many other teenage engineering products, synthesizers, samplers, and effectors. Due to recent troubles, please refrain from purchasing if you wish to pay later, such as with convenience store payment. Also, there have been many cases where I receive messages asking for time to check the operation after arrival, and it is unclear when the receipt evaluation will be, so please only purchase if you can provide a receipt evaluation the day after arrival. 【Product Details】 A micro-sampler with a 40-second sample memory and a built-in recording microphone. Includes audio samples from CAPCOM's game "Street Fighter II". It also has a built-in sequencer and effects function, so you can enjoy making tracks using familiar sounds such as "Hadoken!". Also, despite its pocket size, the unit has a built-in microphone and can record. It also has a sample slice function, so you can perform and create music in a full-fledged manner. In addition to sound effects such as special moves, stage BGM is also included. Melodic Mode You can freely create original melody lines using familiar sounds. Drum Mode You can create original beats by scattering various one-shot drums. Melody Mode Buttons 1-16 represent the musical scale, and in drum mode, each key represents a sound slice.
