"The A4 is an incredibly powerful mono synth that sounds divine. Has incredibly versatile and in depth amount modulation capabilities and sonic potential.

I'd recommend looking at the online specs to get a full run down of this but it has two multimode filters, 3x gorgeous sounding VCOs with 1 and 2 having sub VCOs, A unique 16 step sequencer, two LFOs, a sample and hold module, and the list goes on."

GRPA4 Synthesizer: music and sounds exploration

video uploads by Davide Micheli

"In this series of videos I used the GRPA4 analog synthesizer to explore and experiment some of the sound possibilities in electronic music and beyond.
The GRPA4 is suitable for creating dynamic and very entangled situations in electronic music and sounds.
To emphasize the rhythm and sequence of sounds created with the GRPA4, I inserted a very simple rhythmic pattern of the Roland TR-8S electronic drums machine synchronized via midi with the GRPA4 by means of CUBASE.
In this first video I inserted some initial vocal notes with the GRP 22 Vocoder.
In the other videos of the series dedicated to the GRPA4 that follow, I continue to explore the sound possibilities of the synthesizer arriving, in the last video of the series, to add a part of an chords amrony using a piano. This demonstrates once again the possibility of using electronic synthesizers together with more traditional instruments with success.

ITALIAN
In questa serie di video ho utilizzato il sintetizzatore analogico GRPA4 per esplorare e sperimentare alcune delle possibilità sonore nella musica elettronica e non solo.
Il GRPA4 è adatto per creare situazioni dinamiche e molto intrecciate nella musica elettronica e nei suoni.
Per enfatizzare il ritmo e la sequenza dei suoni creati con il GRPA4, ho inserito un pattern ritmico molto semplice della drum machine elettronica Roland TR-8S sincronizzato via midi con il GRPA4 tramite CUBASE.
In questo primo video ho inserito alcune note vocali iniziali con il Vocoder GRP 22.
Negli altri video della serie dedicati al GRPA4 che seguono, continuo ad esplorare le possibilità sonore del sintetizzatore arrivando, nell'ultimo video della serie, ad aggiungere una parte di un'armonia di accordi utilizzando un pianoforte. Ciò dimostra ancora una volta la possibilità di utilizzare i sintetizzatori elettronici insieme a strumenti più tradizionali con successo."
